Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511646, here are decompositions:

13 + 511633 = 511646
19 + 511627 = 511646
43 + 511603 = 511646
67 + 511579 = 511646
73 + 511573 = 511646
97 + 511549 = 511646
127 + 511519 = 511646
139 + 511507 = 511646

Showing the first eight; more decompositions exist.
