Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539158, here are decompositions:

5 + 539153 = 539158
17 + 539141 = 539158
29 + 539129 = 539158
47 + 539111 = 539158
149 + 539009 = 539158
227 + 538931 = 539158
281 + 538877 = 539158
317 + 538841 = 539158

Showing the first eight; more decompositions exist.
