Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551196, here are decompositions:

23 + 31551173 = 31551196
59 + 31551137 = 31551196
107 + 31551089 = 31551196
197 + 31550999 = 31551196
317 + 31550879 = 31551196
359 + 31550837 = 31551196
389 + 31550807 = 31551196
449 + 31550747 = 31551196

Showing the first eight; more decompositions exist.
