Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621850, here are decompositions:

7 + 8621843 = 8621850
19 + 8621831 = 8621850
23 + 8621827 = 8621850
31 + 8621819 = 8621850
53 + 8621797 = 8621850
71 + 8621779 = 8621850
101 + 8621749 = 8621850
103 + 8621747 = 8621850

Showing the first eight; more decompositions exist.
