Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533774, here are decompositions:

5 + 31533769 = 31533774
11 + 31533763 = 31533774
53 + 31533721 = 31533774
67 + 31533707 = 31533774
113 + 31533661 = 31533774
137 + 31533637 = 31533774
163 + 31533611 = 31533774
193 + 31533581 = 31533774

Showing the first eight; more decompositions exist.
