Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641130, here are decompositions:

37 + 8641093 = 8641130
67 + 8641063 = 8641130
163 + 8640967 = 8641130
181 + 8640949 = 8641130
241 + 8640889 = 8641130
271 + 8640859 = 8641130
307 + 8640823 = 8641130
313 + 8640817 = 8641130

Showing the first eight; more decompositions exist.
