Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509014, here are decompositions:

67 + 31508947 = 31509014
127 + 31508887 = 31509014
151 + 31508863 = 31509014
157 + 31508857 = 31509014
223 + 31508791 = 31509014
283 + 31508731 = 31509014
331 + 31508683 = 31509014
337 + 31508677 = 31509014

Showing the first eight; more decompositions exist.
