Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509446, here are decompositions:

5 + 509441 = 509446
17 + 509429 = 509446
29 + 509417 = 509446
53 + 509393 = 509446
83 + 509363 = 509446
149 + 509297 = 509446
359 + 509087 = 509446
383 + 509063 = 509446

Showing the first eight; more decompositions exist.
