Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612752, here are decompositions:

5 + 31612747 = 31612752
13 + 31612739 = 31612752
19 + 31612733 = 31612752
23 + 31612729 = 31612752
89 + 31612663 = 31612752
131 + 31612621 = 31612752
163 + 31612589 = 31612752
179 + 31612573 = 31612752

Showing the first eight; more decompositions exist.
