Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618340, here are decompositions:

11 + 8618329 = 8618340
13 + 8618327 = 8618340
23 + 8618317 = 8618340
43 + 8618297 = 8618340
47 + 8618293 = 8618340
53 + 8618287 = 8618340
67 + 8618273 = 8618340
83 + 8618257 = 8618340

Showing the first eight; more decompositions exist.
