Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513226, here are decompositions:

23 + 513203 = 513226
53 + 513173 = 513226
59 + 513167 = 513226
89 + 513137 = 513226
167 + 513059 = 513226
173 + 513053 = 513226
179 + 513047 = 513226
227 + 512999 = 513226

Showing the first eight; more decompositions exist.
