Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588694, here are decompositions:

37 + 31588657 = 31588694
211 + 31588483 = 31588694
223 + 31588471 = 31588694
337 + 31588357 = 31588694
373 + 31588321 = 31588694
523 + 31588171 = 31588694
607 + 31588087 = 31588694
691 + 31588003 = 31588694

Showing the first eight; more decompositions exist.
