Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497692, here are decompositions:

13 + 31497679 = 31497692
19 + 31497673 = 31497692
151 + 31497541 = 31497692
223 + 31497469 = 31497692
229 + 31497463 = 31497692
283 + 31497409 = 31497692
379 + 31497313 = 31497692
409 + 31497283 = 31497692

Showing the first eight; more decompositions exist.
