Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492346, here are decompositions:

103 + 31492243 = 31492346
313 + 31492033 = 31492346
433 + 31491913 = 31492346
619 + 31491727 = 31492346
709 + 31491637 = 31492346
727 + 31491619 = 31492346
733 + 31491613 = 31492346
757 + 31491589 = 31492346

Showing the first eight; more decompositions exist.
