Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594722, here are decompositions:

23 + 31594699 = 31594722
31 + 31594691 = 31594722
41 + 31594681 = 31594722
109 + 31594613 = 31594722
113 + 31594609 = 31594722
139 + 31594583 = 31594722
149 + 31594573 = 31594722
233 + 31594489 = 31594722

Showing the first eight; more decompositions exist.
