Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511746, here are decompositions:

23 + 511723 = 511746
43 + 511703 = 511746
113 + 511633 = 511746
163 + 511583 = 511746
167 + 511579 = 511746
173 + 511573 = 511746
197 + 511549 = 511746
223 + 511523 = 511746

Showing the first eight; more decompositions exist.
