Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511758, here are decompositions:

47 + 511711 = 511758
67 + 511691 = 511758
89 + 511669 = 511758
127 + 511631 = 511758
131 + 511627 = 511758
167 + 511591 = 511758
179 + 511579 = 511758
199 + 511559 = 511758

Showing the first eight; more decompositions exist.
