Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510388, here are decompositions:

5 + 510383 = 510388
89 + 510299 = 510388
101 + 510287 = 510388
251 + 510137 = 510388
311 + 510077 = 510388
449 + 509939 = 510388
467 + 509921 = 510388
479 + 509909 = 510388

Showing the first eight; more decompositions exist.
