Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520142, here are decompositions:

13 + 520129 = 520142
19 + 520123 = 520142
31 + 520111 = 520142
79 + 520063 = 520142
199 + 519943 = 520142
211 + 519931 = 520142
223 + 519919 = 520142
349 + 519793 = 520142

Showing the first eight; more decompositions exist.
