Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510758, here are decompositions:

5 + 31510753 = 31510758
67 + 31510691 = 31510758
79 + 31510679 = 31510758
101 + 31510657 = 31510758
127 + 31510631 = 31510758
131 + 31510627 = 31510758
197 + 31510561 = 31510758
241 + 31510517 = 31510758

Showing the first eight; more decompositions exist.
