Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641704, here are decompositions:

7 + 8641697 = 8641704
31 + 8641673 = 8641704
53 + 8641651 = 8641704
61 + 8641643 = 8641704
73 + 8641631 = 8641704
83 + 8641621 = 8641704
101 + 8641603 = 8641704
157 + 8641547 = 8641704

Showing the first eight; more decompositions exist.
