Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596772, here are decompositions:

3 + 31596769 = 31596772
23 + 31596749 = 31596772
29 + 31596743 = 31596772
59 + 31596713 = 31596772
101 + 31596671 = 31596772
353 + 31596419 = 31596772
359 + 31596413 = 31596772
461 + 31596311 = 31596772

Showing the first eight; more decompositions exist.
