Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612550, here are decompositions:

3 + 31612547 = 31612550
19 + 31612531 = 31612550
37 + 31612513 = 31612550
97 + 31612453 = 31612550
127 + 31612423 = 31612550
181 + 31612369 = 31612550
199 + 31612351 = 31612550
241 + 31612309 = 31612550

Showing the first eight; more decompositions exist.
