Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629988, here are decompositions:

7 + 8629981 = 8629988
61 + 8629927 = 8629988
79 + 8629909 = 8629988
97 + 8629891 = 8629988
277 + 8629711 = 8629988
307 + 8629681 = 8629988
337 + 8629651 = 8629988
541 + 8629447 = 8629988

Showing the first eight; more decompositions exist.
