Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482512, here are decompositions:

3 + 31482509 = 31482512
13 + 31482499 = 31482512
73 + 31482439 = 31482512
163 + 31482349 = 31482512
241 + 31482271 = 31482512
283 + 31482229 = 31482512
409 + 31482103 = 31482512
499 + 31482013 = 31482512

Showing the first eight; more decompositions exist.
