Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663690, here are decompositions:

3 + 8663687 = 8663690
37 + 8663653 = 8663690
97 + 8663593 = 8663690
181 + 8663509 = 8663690
193 + 8663497 = 8663690
223 + 8663467 = 8663690
229 + 8663461 = 8663690
379 + 8663311 = 8663690

Showing the first eight; more decompositions exist.
