Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621700, here are decompositions:

7 + 8621693 = 8621700
19 + 8621681 = 8621700
23 + 8621677 = 8621700
47 + 8621653 = 8621700
83 + 8621617 = 8621700
149 + 8621551 = 8621700
223 + 8621477 = 8621700
233 + 8621467 = 8621700

Showing the first eight; more decompositions exist.
