Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596562, here are decompositions:

89 + 31596473 = 31596562
149 + 31596413 = 31596562
251 + 31596311 = 31596562
269 + 31596293 = 31596562
353 + 31596209 = 31596562
419 + 31596143 = 31596562
443 + 31596119 = 31596562
521 + 31596041 = 31596562

Showing the first eight; more decompositions exist.
