Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676320, here are decompositions:

19 + 8676301 = 8676320
97 + 8676223 = 8676320
109 + 8676211 = 8676320
139 + 8676181 = 8676320
151 + 8676169 = 8676320
157 + 8676163 = 8676320
181 + 8676139 = 8676320
241 + 8676079 = 8676320

Showing the first eight; more decompositions exist.
