Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539942, here are decompositions:

43 + 539899 = 539942
61 + 539881 = 539942
79 + 539863 = 539942
103 + 539839 = 539942
181 + 539761 = 539942
199 + 539743 = 539942
229 + 539713 = 539942
313 + 539629 = 539942

Showing the first eight; more decompositions exist.
