Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513166, here are decompositions:

29 + 513137 = 513166
83 + 513083 = 513166
107 + 513059 = 513166
113 + 513053 = 513166
149 + 513017 = 513166
167 + 512999 = 513166
239 + 512927 = 513166
263 + 512903 = 513166

Showing the first eight; more decompositions exist.
