Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596472, here are decompositions:

53 + 31596419 = 31596472
59 + 31596413 = 31596472
71 + 31596401 = 31596472
179 + 31596293 = 31596472
263 + 31596209 = 31596472
353 + 31596119 = 31596472
431 + 31596041 = 31596472
443 + 31596029 = 31596472

Showing the first eight; more decompositions exist.
