Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676278, here are decompositions:

67 + 8676211 = 8676278
97 + 8676181 = 8676278
109 + 8676169 = 8676278
139 + 8676139 = 8676278
199 + 8676079 = 8676278
229 + 8676049 = 8676278
367 + 8675911 = 8676278
409 + 8675869 = 8676278

Showing the first eight; more decompositions exist.
