Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510784, here are decompositions:

11 + 510773 = 510784
17 + 510767 = 510784
101 + 510683 = 510784
107 + 510677 = 510784
167 + 510617 = 510784
173 + 510611 = 510784
233 + 510551 = 510784
383 + 510401 = 510784

Showing the first eight; more decompositions exist.
