Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594736, here are decompositions:

7 + 31594729 = 31594736
37 + 31594699 = 31594736
109 + 31594627 = 31594736
127 + 31594609 = 31594736
139 + 31594597 = 31594736
157 + 31594579 = 31594736
163 + 31594573 = 31594736
307 + 31594429 = 31594736

Showing the first eight; more decompositions exist.
