Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594208, here are decompositions:

127 + 31594081 = 31594208
271 + 31593937 = 31594208
277 + 31593931 = 31594208
307 + 31593901 = 31594208
421 + 31593787 = 31594208
487 + 31593721 = 31594208
577 + 31593631 = 31594208
601 + 31593607 = 31594208

Showing the first eight; more decompositions exist.
