Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539842, here are decompositions:

3 + 539839 = 539842
5 + 539837 = 539842
59 + 539783 = 539842
113 + 539729 = 539842
131 + 539711 = 539842
179 + 539663 = 539842
269 + 539573 = 539842
491 + 539351 = 539842

Showing the first eight; more decompositions exist.
