Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511142, here are decompositions:

19 + 511123 = 511142
31 + 511111 = 511142
103 + 511039 = 511142
109 + 511033 = 511142
199 + 510943 = 511142
211 + 510931 = 511142
223 + 510919 = 511142
349 + 510793 = 511142

Showing the first eight; more decompositions exist.
