Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594888, here are decompositions:

5 + 31594883 = 31594888
11 + 31594877 = 31594888
89 + 31594799 = 31594888
131 + 31594757 = 31594888
197 + 31594691 = 31594888
467 + 31594421 = 31594888
557 + 31594331 = 31594888
617 + 31594271 = 31594888

Showing the first eight; more decompositions exist.
