Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623810, here are decompositions:

3 + 8623807 = 8623810
11 + 8623799 = 8623810
17 + 8623793 = 8623810
23 + 8623787 = 8623810
47 + 8623763 = 8623810
53 + 8623757 = 8623810
59 + 8623751 = 8623810
89 + 8623721 = 8623810

Showing the first eight; more decompositions exist.
