Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594770, here are decompositions:

13 + 31594757 = 31594770
23 + 31594747 = 31594770
41 + 31594729 = 31594770
43 + 31594727 = 31594770
71 + 31594699 = 31594770
79 + 31594691 = 31594770
89 + 31594681 = 31594770
157 + 31594613 = 31594770

Showing the first eight; more decompositions exist.
