Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511146, here are decompositions:

23 + 511123 = 511146
37 + 511109 = 511146
59 + 511087 = 511146
89 + 511057 = 511146
107 + 511039 = 511146
113 + 511033 = 511146
127 + 511019 = 511146
157 + 510989 = 511146

Showing the first eight; more decompositions exist.
