Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676280, here are decompositions:

17 + 8676263 = 8676280
23 + 8676257 = 8676280
29 + 8676251 = 8676280
71 + 8676209 = 8676280
83 + 8676197 = 8676280
149 + 8676131 = 8676280
191 + 8676089 = 8676280
227 + 8676053 = 8676280

Showing the first eight; more decompositions exist.
