Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511826, here are decompositions:

103 + 511723 = 511826
157 + 511669 = 511826
193 + 511633 = 511826
199 + 511627 = 511826
223 + 511603 = 511826
277 + 511549 = 511826
307 + 511519 = 511826
349 + 511477 = 511826

Showing the first eight; more decompositions exist.
