Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511124, here are decompositions:

13 + 511111 = 511124
37 + 511087 = 511124
67 + 511057 = 511124
181 + 510943 = 511124
193 + 510931 = 511124
277 + 510847 = 511124
307 + 510817 = 511124
331 + 510793 = 511124

Showing the first eight; more decompositions exist.
