Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676388, here are decompositions:

5 + 8676383 = 8676388
11 + 8676377 = 8676388
101 + 8676287 = 8676388
107 + 8676281 = 8676388
131 + 8676257 = 8676388
137 + 8676251 = 8676388
179 + 8676209 = 8676388
191 + 8676197 = 8676388

Showing the first eight; more decompositions exist.
