Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632988, here are decompositions:

61 + 8632927 = 8632988
97 + 8632891 = 8632988
157 + 8632831 = 8632988
211 + 8632777 = 8632988
229 + 8632759 = 8632988
271 + 8632717 = 8632988
367 + 8632621 = 8632988
379 + 8632609 = 8632988

Showing the first eight; more decompositions exist.
