Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539668, here are decompositions:

5 + 539663 = 539668
29 + 539639 = 539668
47 + 539621 = 539668
167 + 539501 = 539668
317 + 539351 = 539668
347 + 539321 = 539668
359 + 539309 = 539668
401 + 539267 = 539668

Showing the first eight; more decompositions exist.
