Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683690, here are decompositions:

3 + 8683687 = 8683690
53 + 8683637 = 8683690
83 + 8683607 = 8683690
137 + 8683553 = 8683690
149 + 8683541 = 8683690
167 + 8683523 = 8683690
173 + 8683517 = 8683690
179 + 8683511 = 8683690

Showing the first eight; more decompositions exist.
