Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596510, here are decompositions:

13 + 31596497 = 31596510
37 + 31596473 = 31596510
73 + 31596437 = 31596510
97 + 31596413 = 31596510
107 + 31596403 = 31596510
109 + 31596401 = 31596510
131 + 31596379 = 31596510
193 + 31596317 = 31596510

Showing the first eight; more decompositions exist.
