Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698690, here are decompositions:

17 + 8698673 = 8698690
47 + 8698643 = 8698690
131 + 8698559 = 8698690
137 + 8698553 = 8698690
173 + 8698517 = 8698690
191 + 8698499 = 8698690
197 + 8698493 = 8698690
233 + 8698457 = 8698690

Showing the first eight; more decompositions exist.
