Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509430, here are decompositions:

13 + 509417 = 509430
17 + 509413 = 509430
37 + 509393 = 509430
41 + 509389 = 509430
67 + 509363 = 509430
71 + 509359 = 509430
101 + 509329 = 509430
113 + 509317 = 509430

Showing the first eight; more decompositions exist.
