Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596520, here are decompositions:

23 + 31596497 = 31596520
47 + 31596473 = 31596520
83 + 31596437 = 31596520
101 + 31596419 = 31596520
107 + 31596413 = 31596520
227 + 31596293 = 31596520
311 + 31596209 = 31596520
401 + 31596119 = 31596520

Showing the first eight; more decompositions exist.
