Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640754, here are decompositions:

41 + 8640713 = 8640754
47 + 8640707 = 8640754
53 + 8640701 = 8640754
71 + 8640683 = 8640754
167 + 8640587 = 8640754
251 + 8640503 = 8640754
347 + 8640407 = 8640754
467 + 8640287 = 8640754

Showing the first eight; more decompositions exist.
