Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594798, here are decompositions:

29 + 31594769 = 31594798
41 + 31594757 = 31594798
71 + 31594727 = 31594798
107 + 31594691 = 31594798
251 + 31594547 = 31594798
467 + 31594331 = 31594798
647 + 31594151 = 31594798
701 + 31594097 = 31594798

Showing the first eight; more decompositions exist.
