Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649766, here are decompositions:

3 + 8649763 = 8649766
5 + 8649761 = 8649766
89 + 8649677 = 8649766
137 + 8649629 = 8649766
233 + 8649533 = 8649766
347 + 8649419 = 8649766
383 + 8649383 = 8649766
443 + 8649323 = 8649766

Showing the first eight; more decompositions exist.
