Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640498, here are decompositions:

5 + 8640493 = 8640498
17 + 8640481 = 8640498
47 + 8640451 = 8640498
59 + 8640439 = 8640498
71 + 8640427 = 8640498
79 + 8640419 = 8640498
89 + 8640409 = 8640498
107 + 8640391 = 8640498

Showing the first eight; more decompositions exist.
