Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539238, here are decompositions:

5 + 539233 = 539238
19 + 539219 = 539238
31 + 539207 = 539238
67 + 539171 = 539238
71 + 539167 = 539238
79 + 539159 = 539238
97 + 539141 = 539238
109 + 539129 = 539238

Showing the first eight; more decompositions exist.
