Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509648, here are decompositions:

67 + 509581 = 509648
79 + 509569 = 509648
127 + 509521 = 509648
199 + 509449 = 509648
331 + 509317 = 509648
367 + 509281 = 509648
409 + 509239 = 509648
421 + 509227 = 509648

Showing the first eight; more decompositions exist.
