Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594822, here are decompositions:

11 + 31594811 = 31594822
23 + 31594799 = 31594822
53 + 31594769 = 31594822
131 + 31594691 = 31594822
239 + 31594583 = 31594822
269 + 31594553 = 31594822
359 + 31594463 = 31594822
401 + 31594421 = 31594822

Showing the first eight; more decompositions exist.
