Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632990, here are decompositions:

11 + 8632979 = 8632990
53 + 8632937 = 8632990
59 + 8632931 = 8632990
89 + 8632901 = 8632990
173 + 8632817 = 8632990
263 + 8632727 = 8632990
461 + 8632529 = 8632990
467 + 8632523 = 8632990

Showing the first eight; more decompositions exist.
