Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594870, here are decompositions:

3 + 31594867 = 31594870
59 + 31594811 = 31594870
71 + 31594799 = 31594870
101 + 31594769 = 31594870
113 + 31594757 = 31594870
179 + 31594691 = 31594870
257 + 31594613 = 31594870
317 + 31594553 = 31594870

Showing the first eight; more decompositions exist.
