Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539218, here are decompositions:

11 + 539207 = 539218
47 + 539171 = 539218
59 + 539159 = 539218
89 + 539129 = 539218
107 + 539111 = 539218
179 + 539039 = 539218
347 + 538871 = 539218
389 + 538829 = 539218

Showing the first eight; more decompositions exist.
