Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539640, here are decompositions:

7 + 539633 = 539640
11 + 539629 = 539640
19 + 539621 = 539640
67 + 539573 = 539640
107 + 539533 = 539640
131 + 539509 = 539640
137 + 539503 = 539640
139 + 539501 = 539640

Showing the first eight; more decompositions exist.
