Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641394, here are decompositions:

43 + 8641351 = 8641394
67 + 8641327 = 8641394
163 + 8641231 = 8641394
331 + 8641063 = 8641394
523 + 8640871 = 8641394
571 + 8640823 = 8641394
577 + 8640817 = 8641394
607 + 8640787 = 8641394

Showing the first eight; more decompositions exist.
