Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651700, here are decompositions:

7 + 8651693 = 8651700
11 + 8651689 = 8651700
17 + 8651683 = 8651700
37 + 8651663 = 8651700
53 + 8651647 = 8651700
61 + 8651639 = 8651700
73 + 8651627 = 8651700
97 + 8651603 = 8651700

Showing the first eight; more decompositions exist.
