Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618356, here are decompositions:

17 + 8618339 = 8618356
29 + 8618327 = 8618356
59 + 8618297 = 8618356
83 + 8618273 = 8618356
113 + 8618243 = 8618356
269 + 8618087 = 8618356
293 + 8618063 = 8618356
479 + 8617877 = 8618356

Showing the first eight; more decompositions exist.
