Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590422, here are decompositions:

79 + 31590343 = 31590422
109 + 31590313 = 31590422
181 + 31590241 = 31590422
211 + 31590211 = 31590422
439 + 31589983 = 31590422
499 + 31589923 = 31590422
691 + 31589731 = 31590422
739 + 31589683 = 31590422

Showing the first eight; more decompositions exist.
