Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676172, here are decompositions:

3 + 8676169 = 8676172
41 + 8676131 = 8676172
53 + 8676119 = 8676172
83 + 8676089 = 8676172
101 + 8676071 = 8676172
251 + 8675921 = 8676172
269 + 8675903 = 8676172
293 + 8675879 = 8676172

Showing the first eight; more decompositions exist.
