Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595516, here are decompositions:

109 + 31595407 = 31595516
307 + 31595209 = 31595516
457 + 31595059 = 31595516
613 + 31594903 = 31595516
643 + 31594873 = 31595516
709 + 31594807 = 31595516
769 + 31594747 = 31595516
787 + 31594729 = 31595516

Showing the first eight; more decompositions exist.
