Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631810, here are decompositions:

7 + 8631803 = 8631810
23 + 8631787 = 8631810
29 + 8631781 = 8631810
41 + 8631769 = 8631810
67 + 8631743 = 8631810
73 + 8631737 = 8631810
97 + 8631713 = 8631810
137 + 8631673 = 8631810

Showing the first eight; more decompositions exist.
