Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506518, here are decompositions:

11 + 506507 = 506518
17 + 506501 = 506518
59 + 506459 = 506518
101 + 506417 = 506518
137 + 506381 = 506518
167 + 506351 = 506518
179 + 506339 = 506518
191 + 506327 = 506518

Showing the first eight; more decompositions exist.
