Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594942, here are decompositions:

11 + 31594931 = 31594942
23 + 31594919 = 31594942
59 + 31594883 = 31594942
131 + 31594811 = 31594942
173 + 31594769 = 31594942
251 + 31594691 = 31594942
359 + 31594583 = 31594942
389 + 31594553 = 31594942

Showing the first eight; more decompositions exist.
