Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520050, here are decompositions:

41 + 31520009 = 31520050
113 + 31519937 = 31520050
131 + 31519919 = 31520050
173 + 31519877 = 31520050
227 + 31519823 = 31520050
257 + 31519793 = 31520050
281 + 31519769 = 31520050
347 + 31519703 = 31520050

Showing the first eight; more decompositions exist.
