Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606986, here are decompositions:

23 + 8606963 = 8606986
29 + 8606957 = 8606986
197 + 8606789 = 8606986
257 + 8606729 = 8606986
293 + 8606693 = 8606986
383 + 8606603 = 8606986
449 + 8606537 = 8606986
599 + 8606387 = 8606986

Showing the first eight; more decompositions exist.
