Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594972, here are decompositions:

11 + 31594961 = 31594972
41 + 31594931 = 31594972
53 + 31594919 = 31594972
89 + 31594883 = 31594972
173 + 31594799 = 31594972
281 + 31594691 = 31594972
359 + 31594613 = 31594972
389 + 31594583 = 31594972

Showing the first eight; more decompositions exist.
