Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656630, here are decompositions:

41 + 8656589 = 8656630
53 + 8656577 = 8656630
83 + 8656547 = 8656630
107 + 8656523 = 8656630
113 + 8656517 = 8656630
131 + 8656499 = 8656630
137 + 8656493 = 8656630
149 + 8656481 = 8656630

Showing the first eight; more decompositions exist.
