Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539642, here are decompositions:

3 + 539639 = 539642
13 + 539629 = 539642
109 + 539533 = 539642
139 + 539503 = 539642
163 + 539479 = 539642
193 + 539449 = 539642
241 + 539401 = 539642
331 + 539311 = 539642

Showing the first eight; more decompositions exist.
