Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515296, here are decompositions:

13 + 31515283 = 31515296
79 + 31515217 = 31515296
103 + 31515193 = 31515296
223 + 31515073 = 31515296
229 + 31515067 = 31515296
349 + 31514947 = 31515296
457 + 31514839 = 31515296
607 + 31514689 = 31515296

Showing the first eight; more decompositions exist.
