Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511100, here are decompositions:

13 + 511087 = 511100
43 + 511057 = 511100
61 + 511039 = 511100
67 + 511033 = 511100
157 + 510943 = 511100
181 + 510919 = 511100
193 + 510907 = 511100
211 + 510889 = 511100

Showing the first eight; more decompositions exist.
