Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669278, here are decompositions:

29 + 8669249 = 8669278
41 + 8669237 = 8669278
71 + 8669207 = 8669278
89 + 8669189 = 8669278
251 + 8669027 = 8669278
311 + 8668967 = 8669278
389 + 8668889 = 8669278
461 + 8668817 = 8669278

Showing the first eight; more decompositions exist.
