Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621710, here are decompositions:

3 + 8621707 = 8621710
17 + 8621693 = 8621710
29 + 8621681 = 8621710
101 + 8621609 = 8621710
233 + 8621477 = 8621710
257 + 8621453 = 8621710
281 + 8621429 = 8621710
401 + 8621309 = 8621710

Showing the first eight; more decompositions exist.
