Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517128, here are decompositions:

37 + 517091 = 517128
41 + 517087 = 517128
47 + 517081 = 517128
61 + 517067 = 517128
67 + 517061 = 517128
137 + 516991 = 517128
149 + 516979 = 517128
151 + 516977 = 517128

Showing the first eight; more decompositions exist.
