Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510266, here are decompositions:

13 + 510253 = 510266
19 + 510247 = 510266
67 + 510199 = 510266
109 + 510157 = 510266
139 + 510127 = 510266
193 + 510073 = 510266
199 + 510067 = 510266
277 + 509989 = 510266

Showing the first eight; more decompositions exist.
