Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511262, here are decompositions:

19 + 511243 = 511262
61 + 511201 = 511262
109 + 511153 = 511262
139 + 511123 = 511262
151 + 511111 = 511262
223 + 511039 = 511262
229 + 511033 = 511262
331 + 510931 = 511262

Showing the first eight; more decompositions exist.
