Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756278, here are decompositions:

149 + 8756129 = 8756278
227 + 8756051 = 8756278
239 + 8756039 = 8756278
257 + 8756021 = 8756278
269 + 8756009 = 8756278
281 + 8755997 = 8756278
389 + 8755889 = 8756278
467 + 8755811 = 8756278

Showing the first eight; more decompositions exist.
