Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511278, here are decompositions:

17 + 511261 = 511278
41 + 511237 = 511278
67 + 511211 = 511278
101 + 511177 = 511278
107 + 511171 = 511278
109 + 511169 = 511278
127 + 511151 = 511278
167 + 511111 = 511278

Showing the first eight; more decompositions exist.
