Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539820, here are decompositions:

23 + 539797 = 539820
37 + 539783 = 539820
59 + 539761 = 539820
97 + 539723 = 539820
107 + 539713 = 539820
109 + 539711 = 539820
157 + 539663 = 539820
167 + 539653 = 539820

Showing the first eight; more decompositions exist.
