Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594856, here are decompositions:

43 + 31594813 = 31594856
109 + 31594747 = 31594856
127 + 31594729 = 31594856
157 + 31594699 = 31594856
229 + 31594627 = 31594856
277 + 31594579 = 31594856
283 + 31594573 = 31594856
367 + 31594489 = 31594856

Showing the first eight; more decompositions exist.
