Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641148, here are decompositions:

181 + 8640967 = 8641148
199 + 8640949 = 8641148
277 + 8640871 = 8641148
331 + 8640817 = 8641148
349 + 8640799 = 8641148
367 + 8640781 = 8641148
409 + 8640739 = 8641148
457 + 8640691 = 8641148

Showing the first eight; more decompositions exist.
