Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594758, here are decompositions:

11 + 31594747 = 31594758
29 + 31594729 = 31594758
31 + 31594727 = 31594758
59 + 31594699 = 31594758
67 + 31594691 = 31594758
131 + 31594627 = 31594758
149 + 31594609 = 31594758
179 + 31594579 = 31594758

Showing the first eight; more decompositions exist.
