Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675278, here are decompositions:

89 + 8675189 = 8675278
167 + 8675111 = 8675278
179 + 8675099 = 8675278
251 + 8675027 = 8675278
257 + 8675021 = 8675278
317 + 8674961 = 8675278
389 + 8674889 = 8675278
419 + 8674859 = 8675278

Showing the first eight; more decompositions exist.
