Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640446, here are decompositions:

7 + 8640439 = 8640446
19 + 8640427 = 8640446
37 + 8640409 = 8640446
97 + 8640349 = 8640446
109 + 8640337 = 8640446
277 + 8640169 = 8640446
313 + 8640133 = 8640446
337 + 8640109 = 8640446

Showing the first eight; more decompositions exist.
