Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621862, here are decompositions:

5 + 8621857 = 8621862
19 + 8621843 = 8621862
31 + 8621831 = 8621862
43 + 8621819 = 8621862
83 + 8621779 = 8621862
89 + 8621773 = 8621862
113 + 8621749 = 8621862
181 + 8621681 = 8621862

Showing the first eight; more decompositions exist.
