Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594106, here are decompositions:

43 + 31594063 = 31594106
67 + 31594039 = 31594106
163 + 31593943 = 31594106
463 + 31593643 = 31594106
499 + 31593607 = 31594106
853 + 31593253 = 31594106
997 + 31593109 = 31594106
1009 + 31593097 = 31594106

Showing the first eight; more decompositions exist.
