Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510800, here are decompositions:

7 + 510793 = 510800
109 + 510691 = 510800
181 + 510619 = 510800
211 + 510589 = 510800
271 + 510529 = 510800
337 + 510463 = 510800
349 + 510451 = 510800
397 + 510403 = 510800

Showing the first eight; more decompositions exist.
