Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595132, here are decompositions:

31 + 31595101 = 31595132
73 + 31595059 = 31595132
229 + 31594903 = 31595132
271 + 31594861 = 31595132
433 + 31594699 = 31595132
523 + 31594609 = 31595132
631 + 31594501 = 31595132
643 + 31594489 = 31595132

Showing the first eight; more decompositions exist.
