Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511764, here are decompositions:

7 + 511757 = 511764
41 + 511723 = 511764
53 + 511711 = 511764
61 + 511703 = 511764
73 + 511691 = 511764
131 + 511633 = 511764
137 + 511627 = 511764
173 + 511591 = 511764

Showing the first eight; more decompositions exist.
