Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511072, here are decompositions:

11 + 511061 = 511072
53 + 511019 = 511072
59 + 511013 = 511072
71 + 511001 = 511072
83 + 510989 = 511072
131 + 510941 = 511072
269 + 510803 = 511072
389 + 510683 = 511072

Showing the first eight; more decompositions exist.
