Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641072, here are decompositions:

311 + 8640761 = 8641072
353 + 8640719 = 8641072
359 + 8640713 = 8641072
383 + 8640689 = 8641072
389 + 8640683 = 8641072
569 + 8640503 = 8641072
653 + 8640419 = 8641072
743 + 8640329 = 8641072

Showing the first eight; more decompositions exist.
