Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539988, here are decompositions:

41 + 539947 = 539988
67 + 539921 = 539988
89 + 539899 = 539988
107 + 539881 = 539988
139 + 539849 = 539988
149 + 539839 = 539988
151 + 539837 = 539988
191 + 539797 = 539988

Showing the first eight; more decompositions exist.
