Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595462, here are decompositions:

79 + 31595383 = 31595462
211 + 31595251 = 31595462
463 + 31594999 = 31595462
499 + 31594963 = 31595462
601 + 31594861 = 31595462
733 + 31594729 = 31595462
853 + 31594609 = 31595462
883 + 31594579 = 31595462

Showing the first eight; more decompositions exist.
