Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511922, here are decompositions:

13 + 511909 = 511922
31 + 511891 = 511922
79 + 511843 = 511922
199 + 511723 = 511922
211 + 511711 = 511922
331 + 511591 = 511922
349 + 511573 = 511922
373 + 511549 = 511922

Showing the first eight; more decompositions exist.
