Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635664, here are decompositions:

7 + 8635657 = 8635664
43 + 8635621 = 8635664
97 + 8635567 = 8635664
151 + 8635513 = 8635664
223 + 8635441 = 8635664
241 + 8635423 = 8635664
283 + 8635381 = 8635664
313 + 8635351 = 8635664

Showing the first eight; more decompositions exist.
