Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618908, here are decompositions:

29 + 8618879 = 8618908
41 + 8618867 = 8618908
47 + 8618861 = 8618908
149 + 8618759 = 8618908
227 + 8618681 = 8618908
269 + 8618639 = 8618908
317 + 8618591 = 8618908
479 + 8618429 = 8618908

Showing the first eight; more decompositions exist.
