Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517142, here are decompositions:

13 + 517129 = 517142
61 + 517081 = 517142
139 + 517003 = 517142
151 + 516991 = 517142
163 + 516979 = 517142
193 + 516949 = 517142
211 + 516931 = 517142
271 + 516871 = 517142

Showing the first eight; more decompositions exist.
