Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516264, here are decompositions:

11 + 31516253 = 31516264
23 + 31516241 = 31516264
107 + 31516157 = 31516264
257 + 31516007 = 31516264
383 + 31515881 = 31516264
443 + 31515821 = 31516264
587 + 31515677 = 31516264
617 + 31515647 = 31516264

Showing the first eight; more decompositions exist.
