Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492376, here are decompositions:

7 + 31492369 = 31492376
163 + 31492213 = 31492376
283 + 31492093 = 31492376
463 + 31491913 = 31492376
739 + 31491637 = 31492376
757 + 31491619 = 31492376
787 + 31491589 = 31492376
829 + 31491547 = 31492376

Showing the first eight; more decompositions exist.
