Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640494, here are decompositions:

13 + 8640481 = 8640494
43 + 8640451 = 8640494
67 + 8640427 = 8640494
103 + 8640391 = 8640494
157 + 8640337 = 8640494
283 + 8640211 = 8640494
307 + 8640187 = 8640494
571 + 8639923 = 8640494

Showing the first eight; more decompositions exist.
