Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511842, here are decompositions:

11 + 511831 = 511842
31 + 511811 = 511842
41 + 511801 = 511842
131 + 511711 = 511842
139 + 511703 = 511842
151 + 511691 = 511842
173 + 511669 = 511842
211 + 511631 = 511842

Showing the first eight; more decompositions exist.
