Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737644, here are decompositions:

17 + 8737627 = 8737644
53 + 8737591 = 8737644
61 + 8737583 = 8737644
67 + 8737577 = 8737644
73 + 8737571 = 8737644
101 + 8737543 = 8737644
163 + 8737481 = 8737644
191 + 8737453 = 8737644

Showing the first eight; more decompositions exist.
