Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513244, here are decompositions:

5 + 513239 = 513244
41 + 513203 = 513244
71 + 513173 = 513244
107 + 513137 = 513244
113 + 513131 = 513244
191 + 513053 = 513244
197 + 513047 = 513244
227 + 513017 = 513244

Showing the first eight; more decompositions exist.
