Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738170, here are decompositions:

41 + 8738129 = 8738170
47 + 8738123 = 8738170
83 + 8738087 = 8738170
137 + 8738033 = 8738170
191 + 8737979 = 8738170
227 + 8737943 = 8738170
461 + 8737709 = 8738170
503 + 8737667 = 8738170

Showing the first eight; more decompositions exist.
