Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596544, here are decompositions:

3 + 31596541 = 31596544
47 + 31596497 = 31596544
71 + 31596473 = 31596544
107 + 31596437 = 31596544
131 + 31596413 = 31596544
227 + 31596317 = 31596544
233 + 31596311 = 31596544
251 + 31596293 = 31596544

Showing the first eight; more decompositions exist.
