Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512090, here are decompositions:

31 + 512059 = 512090
43 + 512047 = 512090
79 + 512011 = 512090
127 + 511963 = 512090
151 + 511939 = 512090
157 + 511933 = 512090
181 + 511909 = 512090
193 + 511897 = 512090

Showing the first eight; more decompositions exist.
