Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511894, here are decompositions:

3 + 511891 = 511894
83 + 511811 = 511894
101 + 511793 = 511894
107 + 511787 = 511894
137 + 511757 = 511894
191 + 511703 = 511894
263 + 511631 = 511894
311 + 511583 = 511894

Showing the first eight; more decompositions exist.
