Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512042, here are decompositions:

31 + 512011 = 512042
79 + 511963 = 512042
103 + 511939 = 512042
109 + 511933 = 512042
151 + 511891 = 512042
199 + 511843 = 512042
211 + 511831 = 512042
241 + 511801 = 512042

Showing the first eight; more decompositions exist.
