Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590552, here are decompositions:

53 + 31590499 = 31590552
73 + 31590479 = 31590552
83 + 31590469 = 31590552
89 + 31590463 = 31590552
101 + 31590451 = 31590552
109 + 31590443 = 31590552
131 + 31590421 = 31590552
139 + 31590413 = 31590552

Showing the first eight; more decompositions exist.
