Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612410, here are decompositions:

19 + 31612391 = 31612410
29 + 31612381 = 31612410
41 + 31612369 = 31612410
47 + 31612363 = 31612410
59 + 31612351 = 31612410
97 + 31612313 = 31612410
101 + 31612309 = 31612410
103 + 31612307 = 31612410

Showing the first eight; more decompositions exist.
