Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539678, here are decompositions:

37 + 539641 = 539678
199 + 539479 = 539678
229 + 539449 = 539678
277 + 539401 = 539678
331 + 539347 = 539678
367 + 539311 = 539678
409 + 539269 = 539678
571 + 539107 = 539678

Showing the first eight; more decompositions exist.
