Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676380, here are decompositions:

3 + 8676377 = 8676380
19 + 8676361 = 8676380
43 + 8676337 = 8676380
61 + 8676319 = 8676380
79 + 8676301 = 8676380
151 + 8676229 = 8676380
157 + 8676223 = 8676380
199 + 8676181 = 8676380

Showing the first eight; more decompositions exist.
