Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676220, here are decompositions:

11 + 8676209 = 8676220
23 + 8676197 = 8676220
89 + 8676131 = 8676220
101 + 8676119 = 8676220
131 + 8676089 = 8676220
149 + 8676071 = 8676220
167 + 8676053 = 8676220
191 + 8676029 = 8676220

Showing the first eight; more decompositions exist.
