Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728672, here are decompositions:

23 + 8728649 = 8728672
101 + 8728571 = 8728672
191 + 8728481 = 8728672
383 + 8728289 = 8728672
431 + 8728241 = 8728672
461 + 8728211 = 8728672
479 + 8728193 = 8728672
503 + 8728169 = 8728672

Showing the first eight; more decompositions exist.
