Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539940, here are decompositions:

19 + 539921 = 539940
41 + 539899 = 539940
43 + 539897 = 539940
59 + 539881 = 539940
97 + 539843 = 539940
101 + 539839 = 539940
103 + 539837 = 539940
157 + 539783 = 539940

Showing the first eight; more decompositions exist.
