Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510208, here are decompositions:

5 + 510203 = 510208
29 + 510179 = 510208
71 + 510137 = 510208
107 + 510101 = 510208
131 + 510077 = 510208
269 + 509939 = 510208
467 + 509741 = 510208
509 + 509699 = 510208

Showing the first eight; more decompositions exist.
