Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511716, here are decompositions:

5 + 511711 = 511716
13 + 511703 = 511716
47 + 511669 = 511716
83 + 511633 = 511716
89 + 511627 = 511716
113 + 511603 = 511716
137 + 511579 = 511716
157 + 511559 = 511716

Showing the first eight; more decompositions exist.
