Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621834, here are decompositions:

3 + 8621831 = 8621834
7 + 8621827 = 8621834
37 + 8621797 = 8621834
61 + 8621773 = 8621834
127 + 8621707 = 8621834
157 + 8621677 = 8621834
181 + 8621653 = 8621834
211 + 8621623 = 8621834

Showing the first eight; more decompositions exist.
