Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511712, here are decompositions:

43 + 511669 = 511712
79 + 511633 = 511712
109 + 511603 = 511712
139 + 511573 = 511712
163 + 511549 = 511712
193 + 511519 = 511712
379 + 511333 = 511712
433 + 511279 = 511712

Showing the first eight; more decompositions exist.
