Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640718, here are decompositions:

5 + 8640713 = 8640718
11 + 8640707 = 8640718
17 + 8640701 = 8640718
29 + 8640689 = 8640718
131 + 8640587 = 8640718
311 + 8640407 = 8640718
389 + 8640329 = 8640718
431 + 8640287 = 8640718

Showing the first eight; more decompositions exist.
