Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510478, here are decompositions:

29 + 510449 = 510478
167 + 510311 = 510478
179 + 510299 = 510478
191 + 510287 = 510478
251 + 510227 = 510478
389 + 510089 = 510478
401 + 510077 = 510478
431 + 510047 = 510478

Showing the first eight; more decompositions exist.
