Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511706, here are decompositions:

3 + 511703 = 511706
37 + 511669 = 511706
73 + 511633 = 511706
79 + 511627 = 511706
103 + 511603 = 511706
127 + 511579 = 511706
157 + 511549 = 511706
199 + 511507 = 511706

Showing the first eight; more decompositions exist.
