Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520134, here are decompositions:

17 + 31520117 = 31520134
197 + 31519937 = 31520134
257 + 31519877 = 31520134
311 + 31519823 = 31520134
431 + 31519703 = 31520134
461 + 31519673 = 31520134
563 + 31519571 = 31520134
647 + 31519487 = 31520134

Showing the first eight; more decompositions exist.
