Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641346, here are decompositions:

19 + 8641327 = 8641346
37 + 8641309 = 8641346
73 + 8641273 = 8641346
97 + 8641249 = 8641346
199 + 8641147 = 8641346
283 + 8641063 = 8641346
379 + 8640967 = 8641346
397 + 8640949 = 8641346

Showing the first eight; more decompositions exist.
