Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509406, here are decompositions:

13 + 509393 = 509406
17 + 509389 = 509406
43 + 509363 = 509406
47 + 509359 = 509406
89 + 509317 = 509406
109 + 509297 = 509406
113 + 509293 = 509406
167 + 509239 = 509406

Showing the first eight; more decompositions exist.
