Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728604, here are decompositions:

7 + 8728597 = 8728604
13 + 8728591 = 8728604
223 + 8728381 = 8728604
331 + 8728273 = 8728604
397 + 8728207 = 8728604
457 + 8728147 = 8728604
673 + 8727931 = 8728604
691 + 8727913 = 8728604

Showing the first eight; more decompositions exist.
