Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622940, here are decompositions:

17 + 8622923 = 8622940
83 + 8622857 = 8622940
173 + 8622767 = 8622940
233 + 8622707 = 8622940
257 + 8622683 = 8622940
419 + 8622521 = 8622940
449 + 8622491 = 8622940
467 + 8622473 = 8622940

Showing the first eight; more decompositions exist.
