Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552516, here are decompositions:

29 + 31552487 = 31552516
113 + 31552403 = 31552516
263 + 31552253 = 31552516
389 + 31552127 = 31552516
467 + 31552049 = 31552516
557 + 31551959 = 31552516
659 + 31551857 = 31552516
887 + 31551629 = 31552516

Showing the first eight; more decompositions exist.
