Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693690, here are decompositions:

3 + 8693687 = 8693690
13 + 8693677 = 8693690
37 + 8693653 = 8693690
67 + 8693623 = 8693690
73 + 8693617 = 8693690
139 + 8693551 = 8693690
199 + 8693491 = 8693690
223 + 8693467 = 8693690

Showing the first eight; more decompositions exist.
