Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511078, here are decompositions:

17 + 511061 = 511078
59 + 511019 = 511078
89 + 510989 = 511078
137 + 510941 = 511078
251 + 510827 = 511078
311 + 510767 = 511078
401 + 510677 = 511078
461 + 510617 = 511078

Showing the first eight; more decompositions exist.
