Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511668, here are decompositions:

37 + 511631 = 511668
41 + 511627 = 511668
89 + 511579 = 511668
109 + 511559 = 511668
127 + 511541 = 511668
149 + 511519 = 511668
181 + 511487 = 511668
191 + 511477 = 511668

Showing the first eight; more decompositions exist.
