Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640592, here are decompositions:

5 + 8640587 = 8640592
89 + 8640503 = 8640592
173 + 8640419 = 8640592
263 + 8640329 = 8640592
431 + 8640161 = 8640592
641 + 8639951 = 8640592
683 + 8639909 = 8640592
743 + 8639849 = 8640592

Showing the first eight; more decompositions exist.
