Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510346, here are decompositions:

37 + 31510309 = 31510346
103 + 31510243 = 31510346
337 + 31510009 = 31510346
379 + 31509967 = 31510346
397 + 31509949 = 31510346
433 + 31509913 = 31510346
457 + 31509889 = 31510346
463 + 31509883 = 31510346

Showing the first eight; more decompositions exist.
