Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635678, here are decompositions:

5 + 8635673 = 8635678
11 + 8635667 = 8635678
41 + 8635637 = 8635678
47 + 8635631 = 8635678
71 + 8635607 = 8635678
269 + 8635409 = 8635678
419 + 8635259 = 8635678
479 + 8635199 = 8635678

Showing the first eight; more decompositions exist.
