Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509096, here are decompositions:

5 + 31509091 = 31509096
19 + 31509077 = 31509096
43 + 31509053 = 31509096
67 + 31509029 = 31509096
79 + 31509017 = 31509096
97 + 31508999 = 31509096
137 + 31508959 = 31509096
149 + 31508947 = 31509096

Showing the first eight; more decompositions exist.
