Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622068, here are decompositions:

89 + 31621979 = 31622068
167 + 31621901 = 31622068
389 + 31621679 = 31622068
431 + 31621637 = 31622068
509 + 31621559 = 31622068
641 + 31621427 = 31622068
701 + 31621367 = 31622068
809 + 31621259 = 31622068

Showing the first eight; more decompositions exist.
