Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539172, here are decompositions:

5 + 539167 = 539172
13 + 539159 = 539172
19 + 539153 = 539172
31 + 539141 = 539172
43 + 539129 = 539172
59 + 539113 = 539172
61 + 539111 = 539172
71 + 539101 = 539172

Showing the first eight; more decompositions exist.
