Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646610, here are decompositions:

3 + 8646607 = 8646610
29 + 8646581 = 8646610
107 + 8646503 = 8646610
113 + 8646497 = 8646610
131 + 8646479 = 8646610
233 + 8646377 = 8646610
281 + 8646329 = 8646610
293 + 8646317 = 8646610

Showing the first eight; more decompositions exist.
