Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640480, here are decompositions:

29 + 8640451 = 8640480
41 + 8640439 = 8640480
53 + 8640427 = 8640480
61 + 8640419 = 8640480
71 + 8640409 = 8640480
73 + 8640407 = 8640480
89 + 8640391 = 8640480
131 + 8640349 = 8640480

Showing the first eight; more decompositions exist.
