Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594526, here are decompositions:

37 + 31594489 = 31594526
97 + 31594429 = 31594526
127 + 31594399 = 31594526
193 + 31594333 = 31594526
367 + 31594159 = 31594526
463 + 31594063 = 31594526
487 + 31594039 = 31594526
739 + 31593787 = 31594526

Showing the first eight; more decompositions exist.
