Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622614, here are decompositions:

431 + 31622183 = 31622614
461 + 31622153 = 31622614
467 + 31622147 = 31622614
911 + 31621703 = 31622614
941 + 31621673 = 31622614
953 + 31621661 = 31622614
977 + 31621637 = 31622614
983 + 31621631 = 31622614

Showing the first eight; more decompositions exist.
