Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509196, here are decompositions:

23 + 31509173 = 31509196
167 + 31509029 = 31509196
179 + 31509017 = 31509196
197 + 31508999 = 31509196
353 + 31508843 = 31509196
449 + 31508747 = 31509196
557 + 31508639 = 31509196
617 + 31508579 = 31509196

Showing the first eight; more decompositions exist.
