Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594988, here are decompositions:

127 + 31594861 = 31594988
181 + 31594807 = 31594988
241 + 31594747 = 31594988
307 + 31594681 = 31594988
379 + 31594609 = 31594988
409 + 31594579 = 31594988
487 + 31594501 = 31594988
499 + 31594489 = 31594988

Showing the first eight; more decompositions exist.
