Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634640, here are decompositions:

11 + 8634629 = 8634640
23 + 8634617 = 8634640
59 + 8634581 = 8634640
83 + 8634557 = 8634640
89 + 8634551 = 8634640
101 + 8634539 = 8634640
137 + 8634503 = 8634640
173 + 8634467 = 8634640

Showing the first eight; more decompositions exist.
