Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618310, here are decompositions:

13 + 8618297 = 8618310
17 + 8618293 = 8618310
23 + 8618287 = 8618310
37 + 8618273 = 8618310
53 + 8618257 = 8618310
59 + 8618251 = 8618310
67 + 8618243 = 8618310
73 + 8618237 = 8618310

Showing the first eight; more decompositions exist.
