Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511736, here are decompositions:

13 + 511723 = 511736
67 + 511669 = 511736
103 + 511633 = 511736
109 + 511627 = 511736
157 + 511579 = 511736
163 + 511573 = 511736
229 + 511507 = 511736
283 + 511453 = 511736

Showing the first eight; more decompositions exist.
