Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511090, here are decompositions:

3 + 511087 = 511090
29 + 511061 = 511090
71 + 511019 = 511090
89 + 511001 = 511090
101 + 510989 = 511090
149 + 510941 = 511090
263 + 510827 = 511090
317 + 510773 = 511090

Showing the first eight; more decompositions exist.
