Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704644, here are decompositions:

23 + 8704621 = 8704644
31 + 8704613 = 8704644
37 + 8704607 = 8704644
43 + 8704601 = 8704644
97 + 8704547 = 8704644
131 + 8704513 = 8704644
163 + 8704481 = 8704644
211 + 8704433 = 8704644

Showing the first eight; more decompositions exist.
