Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630810, here are decompositions:

31 + 8630779 = 8630810
61 + 8630749 = 8630810
73 + 8630737 = 8630810
127 + 8630683 = 8630810
157 + 8630653 = 8630810
163 + 8630647 = 8630810
211 + 8630599 = 8630810
367 + 8630443 = 8630810

Showing the first eight; more decompositions exist.
