Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728136, here are decompositions:

7 + 8728129 = 8728136
199 + 8727937 = 8728136
223 + 8727913 = 8728136
229 + 8727907 = 8728136
379 + 8727757 = 8728136
409 + 8727727 = 8728136
463 + 8727673 = 8728136
607 + 8727529 = 8728136

Showing the first eight; more decompositions exist.
