Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510142, here are decompositions:

5 + 510137 = 510142
41 + 510101 = 510142
53 + 510089 = 510142
179 + 509963 = 510142
233 + 509909 = 510142
263 + 509879 = 510142
359 + 509783 = 510142
401 + 509741 = 510142

Showing the first eight; more decompositions exist.
