Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612368, here are decompositions:

5 + 31612363 = 31612368
17 + 31612351 = 31612368
59 + 31612309 = 31612368
61 + 31612307 = 31612368
127 + 31612241 = 31612368
167 + 31612201 = 31612368
457 + 31611911 = 31612368
461 + 31611907 = 31612368

Showing the first eight; more decompositions exist.
