Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595342, here are decompositions:

241 + 31595101 = 31595342
283 + 31595059 = 31595342
379 + 31594963 = 31595342
439 + 31594903 = 31595342
613 + 31594729 = 31595342
643 + 31594699 = 31595342
661 + 31594681 = 31595342
733 + 31594609 = 31595342

Showing the first eight; more decompositions exist.
