Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594858, here are decompositions:

47 + 31594811 = 31594858
59 + 31594799 = 31594858
89 + 31594769 = 31594858
101 + 31594757 = 31594858
131 + 31594727 = 31594858
167 + 31594691 = 31594858
311 + 31594547 = 31594858
587 + 31594271 = 31594858

Showing the first eight; more decompositions exist.
