Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539138, here are decompositions:

31 + 539107 = 539138
37 + 539101 = 539138
151 + 538987 = 539138
199 + 538939 = 539138
211 + 538927 = 539138
337 + 538801 = 539138
349 + 538789 = 539138
367 + 538771 = 539138

Showing the first eight; more decompositions exist.
