Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511688, here are decompositions:

19 + 511669 = 511688
61 + 511627 = 511688
97 + 511591 = 511688
109 + 511579 = 511688
139 + 511549 = 511688
181 + 511507 = 511688
211 + 511477 = 511688
241 + 511447 = 511688

Showing the first eight; more decompositions exist.
