Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640626, here are decompositions:

67 + 8640559 = 8640626
73 + 8640553 = 8640626
79 + 8640547 = 8640626
199 + 8640427 = 8640626
277 + 8640349 = 8640626
367 + 8640259 = 8640626
439 + 8640187 = 8640626
457 + 8640169 = 8640626

Showing the first eight; more decompositions exist.
