Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539644, here are decompositions:

3 + 539641 = 539644
5 + 539639 = 539644
11 + 539633 = 539644
23 + 539621 = 539644
71 + 539573 = 539644
137 + 539507 = 539644
197 + 539447 = 539644
293 + 539351 = 539644

Showing the first eight; more decompositions exist.
