Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461612, here are decompositions:

41 + 31461571 = 31461612
43 + 31461569 = 31461612
59 + 31461553 = 31461612
79 + 31461533 = 31461612
89 + 31461523 = 31461612
131 + 31461481 = 31461612
199 + 31461413 = 31461612
251 + 31461361 = 31461612

Showing the first eight; more decompositions exist.
