Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517138, here are decompositions:

47 + 517091 = 517138
59 + 517079 = 517138
71 + 517067 = 517138
179 + 516959 = 517138
191 + 516947 = 517138
227 + 516911 = 517138
317 + 516821 = 517138
449 + 516689 = 517138

Showing the first eight; more decompositions exist.
