Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510172, here are decompositions:

71 + 510101 = 510172
83 + 510089 = 510172
233 + 509939 = 510172
251 + 509921 = 510172
263 + 509909 = 510172
293 + 509879 = 510172
389 + 509783 = 510172
431 + 509741 = 510172

Showing the first eight; more decompositions exist.
