Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520696, here are decompositions:

37 + 31520659 = 31520696
79 + 31520617 = 31520696
127 + 31520569 = 31520696
199 + 31520497 = 31520696
307 + 31520389 = 31520696
379 + 31520317 = 31520696
397 + 31520299 = 31520696
463 + 31520233 = 31520696

Showing the first eight; more decompositions exist.
