Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590582, here are decompositions:

11 + 31590571 = 31590582
31 + 31590551 = 31590582
83 + 31590499 = 31590582
103 + 31590479 = 31590582
113 + 31590469 = 31590582
131 + 31590451 = 31590582
139 + 31590443 = 31590582
181 + 31590401 = 31590582

Showing the first eight; more decompositions exist.
