Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596372, here are decompositions:

61 + 31596311 = 31596372
79 + 31596293 = 31596372
163 + 31596209 = 31596372
179 + 31596193 = 31596372
229 + 31596143 = 31596372
251 + 31596121 = 31596372
331 + 31596041 = 31596372
383 + 31595989 = 31596372

Showing the first eight; more decompositions exist.
