Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673680, here are decompositions:

3 + 8673677 = 8673680
79 + 8673601 = 8673680
109 + 8673571 = 8673680
163 + 8673517 = 8673680
181 + 8673499 = 8673680
307 + 8673373 = 8673680
409 + 8673271 = 8673680
523 + 8673157 = 8673680

Showing the first eight; more decompositions exist.
