Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539142, here are decompositions:

13 + 539129 = 539142
29 + 539113 = 539142
31 + 539111 = 539142
41 + 539101 = 539142
53 + 539089 = 539142
103 + 539039 = 539142
139 + 539003 = 539142
199 + 538943 = 539142

Showing the first eight; more decompositions exist.
