Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564936, here are decompositions:

3 + 31564933 = 31564936
17 + 31564919 = 31564936
83 + 31564853 = 31564936
167 + 31564769 = 31564936
197 + 31564739 = 31564936
419 + 31564517 = 31564936
503 + 31564433 = 31564936
773 + 31564163 = 31564936

Showing the first eight; more decompositions exist.
