Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539420, here are decompositions:

19 + 539401 = 539420
31 + 539389 = 539420
73 + 539347 = 539420
97 + 539323 = 539420
109 + 539311 = 539420
127 + 539293 = 539420
151 + 539269 = 539420
307 + 539113 = 539420

Showing the first eight; more decompositions exist.
