Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511656, here are decompositions:

23 + 511633 = 511656
29 + 511627 = 511656
53 + 511603 = 511656
73 + 511583 = 511656
83 + 511573 = 511656
97 + 511559 = 511656
107 + 511549 = 511656
137 + 511519 = 511656

Showing the first eight; more decompositions exist.
