Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594730, here are decompositions:

3 + 31594727 = 31594730
31 + 31594699 = 31594730
103 + 31594627 = 31594730
151 + 31594579 = 31594730
157 + 31594573 = 31594730
229 + 31594501 = 31594730
241 + 31594489 = 31594730
331 + 31594399 = 31594730

Showing the first eight; more decompositions exist.
