Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590540, here are decompositions:

41 + 31590499 = 31590540
53 + 31590487 = 31590540
61 + 31590479 = 31590540
71 + 31590469 = 31590540
73 + 31590467 = 31590540
89 + 31590451 = 31590540
97 + 31590443 = 31590540
127 + 31590413 = 31590540

Showing the first eight; more decompositions exist.
