Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511208, here are decompositions:

7 + 511201 = 511208
31 + 511177 = 511208
37 + 511171 = 511208
97 + 511111 = 511208
151 + 511057 = 511208
277 + 510931 = 511208
457 + 510751 = 511208
499 + 510709 = 511208

Showing the first eight; more decompositions exist.
