Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517158, here are decompositions:

7 + 517151 = 517158
29 + 517129 = 517158
67 + 517091 = 517158
71 + 517087 = 517158
79 + 517079 = 517158
97 + 517061 = 517158
167 + 516991 = 517158
179 + 516979 = 517158

Showing the first eight; more decompositions exist.
