Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642560, here are decompositions:

41 + 8642519 = 8642560
53 + 8642507 = 8642560
71 + 8642489 = 8642560
107 + 8642453 = 8642560
131 + 8642429 = 8642560
257 + 8642303 = 8642560
401 + 8642159 = 8642560
419 + 8642141 = 8642560

Showing the first eight; more decompositions exist.
