Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512830, here are decompositions:

11 + 512819 = 512830
83 + 512747 = 512830
89 + 512741 = 512830
113 + 512717 = 512830
167 + 512663 = 512830
173 + 512657 = 512830
233 + 512597 = 512830
239 + 512591 = 512830

Showing the first eight; more decompositions exist.
