Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515096, here are decompositions:

17 + 31515079 = 31515096
23 + 31515073 = 31515096
29 + 31515067 = 31515096
73 + 31515023 = 31515096
89 + 31515007 = 31515096
97 + 31514999 = 31515096
127 + 31514969 = 31515096
149 + 31514947 = 31515096

Showing the first eight; more decompositions exist.
