Search a number in a sentence

Hello Experts, I need help please, I need a formula to search a number in a sentence. Example: In row 1, I will search a number that is greater than 50 (50 can be change anytime by the user from 1 to 300), so the answer is 150, 100, 75 & 201. The formula will be applicable from row 1 to row 5. In row 4, the answer is 135, 160 & 165. Thank you, Carlito
