Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492696, here are decompositions:

5 + 31492691 = 31492696
29 + 31492667 = 31492696
167 + 31492529 = 31492696
293 + 31492403 = 31492696
359 + 31492337 = 31492696
419 + 31492277 = 31492696
617 + 31492079 = 31492696
947 + 31491749 = 31492696

Showing the first eight; more decompositions exist.
