Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640600, here are decompositions:

13 + 8640587 = 8640600
41 + 8640559 = 8640600
47 + 8640553 = 8640600
53 + 8640547 = 8640600
97 + 8640503 = 8640600
107 + 8640493 = 8640600
149 + 8640451 = 8640600
173 + 8640427 = 8640600

Showing the first eight; more decompositions exist.
