Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622988, here are decompositions:

5 + 8622983 = 8622988
29 + 8622959 = 8622988
131 + 8622857 = 8622988
281 + 8622707 = 8622988
467 + 8622521 = 8622988
701 + 8622287 = 8622988
797 + 8622191 = 8622988
947 + 8622041 = 8622988

Showing the first eight; more decompositions exist.
