Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510878, here are decompositions:

31 + 510847 = 510878
61 + 510817 = 510878
127 + 510751 = 510878
349 + 510529 = 510878
397 + 510481 = 510878
421 + 510457 = 510878
499 + 510379 = 510878
547 + 510331 = 510878

Showing the first eight; more decompositions exist.
