Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511020, here are decompositions:

7 + 511013 = 511020
19 + 511001 = 511020
31 + 510989 = 511020
79 + 510941 = 511020
89 + 510931 = 511020
101 + 510919 = 511020
113 + 510907 = 511020
131 + 510889 = 511020

Showing the first eight; more decompositions exist.
