Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605922, here are decompositions:

113 + 31605809 = 31605922
149 + 31605773 = 31605922
233 + 31605689 = 31605922
431 + 31605491 = 31605922
479 + 31605443 = 31605922
503 + 31605419 = 31605922
521 + 31605401 = 31605922
659 + 31605263 = 31605922

Showing the first eight; more decompositions exist.
