Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739656, here are decompositions:

19 + 8739637 = 8739656
73 + 8739583 = 8739656
127 + 8739529 = 8739656
157 + 8739499 = 8739656
193 + 8739463 = 8739656
223 + 8739433 = 8739656
307 + 8739349 = 8739656
463 + 8739193 = 8739656

Showing the first eight; more decompositions exist.
