Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539428, here are decompositions:

89 + 539339 = 539428
107 + 539321 = 539428
167 + 539261 = 539428
191 + 539237 = 539428
257 + 539171 = 539428
269 + 539159 = 539428
317 + 539111 = 539428
389 + 539039 = 539428

Showing the first eight; more decompositions exist.
