Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539666, here are decompositions:

3 + 539663 = 539666
13 + 539653 = 539666
37 + 539629 = 539666
157 + 539509 = 539666
163 + 539503 = 539666
277 + 539389 = 539666
373 + 539293 = 539666
397 + 539269 = 539666

Showing the first eight; more decompositions exist.
