Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511188, here are decompositions:

11 + 511177 = 511188
17 + 511171 = 511188
19 + 511169 = 511188
37 + 511151 = 511188
79 + 511109 = 511188
101 + 511087 = 511188
127 + 511061 = 511188
131 + 511057 = 511188

Showing the first eight; more decompositions exist.
