Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641298, here are decompositions:

67 + 8641231 = 8641298
151 + 8641147 = 8641298
331 + 8640967 = 8641298
349 + 8640949 = 8641298
409 + 8640889 = 8641298
439 + 8640859 = 8641298
499 + 8640799 = 8641298
607 + 8640691 = 8641298

Showing the first eight; more decompositions exist.
