Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641304, here are decompositions:

3 + 8641301 = 8641304
31 + 8641273 = 8641304
73 + 8641231 = 8641304
157 + 8641147 = 8641304
211 + 8641093 = 8641304
241 + 8641063 = 8641304
337 + 8640967 = 8641304
421 + 8640883 = 8641304

Showing the first eight; more decompositions exist.
