Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464396, here are decompositions:

37 + 31464359 = 31464396
127 + 31464269 = 31464396
163 + 31464233 = 31464396
317 + 31464079 = 31464396
349 + 31464047 = 31464396
433 + 31463963 = 31464396
487 + 31463909 = 31464396
499 + 31463897 = 31464396

Showing the first eight; more decompositions exist.
