Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736656, here are decompositions:

3 + 8736653 = 8736656
73 + 8736583 = 8736656
109 + 8736547 = 8736656
127 + 8736529 = 8736656
193 + 8736463 = 8736656
223 + 8736433 = 8736656
433 + 8736223 = 8736656
457 + 8736199 = 8736656

Showing the first eight; more decompositions exist.
