Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510154, here are decompositions:

17 + 510137 = 510154
53 + 510101 = 510154
107 + 510047 = 510154
191 + 509963 = 510154
233 + 509921 = 510154
311 + 509843 = 510154
317 + 509837 = 510154
353 + 509801 = 510154

Showing the first eight; more decompositions exist.
