Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513906, here are decompositions:

7 + 513899 = 513906
67 + 513839 = 513906
137 + 513769 = 513906
139 + 513767 = 513906
157 + 513749 = 513906
167 + 513739 = 513906
179 + 513727 = 513906
223 + 513683 = 513906

Showing the first eight; more decompositions exist.
