Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522012, here are decompositions:

59 + 31521953 = 31522012
149 + 31521863 = 31522012
419 + 31521593 = 31522012
503 + 31521509 = 31522012
563 + 31521449 = 31522012
593 + 31521419 = 31522012
653 + 31521359 = 31522012
659 + 31521353 = 31522012

Showing the first eight; more decompositions exist.
