Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738188, here are decompositions:

59 + 8738129 = 8738188
101 + 8738087 = 8738188
317 + 8737871 = 8738188
359 + 8737829 = 8738188
479 + 8737709 = 8738188
491 + 8737697 = 8738188
521 + 8737667 = 8738188
617 + 8737571 = 8738188

Showing the first eight; more decompositions exist.
