Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630420, here are decompositions:

3 + 8630417 = 8630420
109 + 8630311 = 8630420
151 + 8630269 = 8630420
181 + 8630239 = 8630420
229 + 8630191 = 8630420
241 + 8630179 = 8630420
307 + 8630113 = 8630420
349 + 8630071 = 8630420

Showing the first eight; more decompositions exist.
