Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612756, here are decompositions:

3 + 31612753 = 31612756
17 + 31612739 = 31612756
23 + 31612733 = 31612756
29 + 31612727 = 31612756
89 + 31612667 = 31612756
137 + 31612619 = 31612756
167 + 31612589 = 31612756
173 + 31612583 = 31612756

Showing the first eight; more decompositions exist.
