Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509442, here are decompositions:

13 + 509429 = 509442
29 + 509413 = 509442
53 + 509389 = 509442
79 + 509363 = 509442
83 + 509359 = 509442
113 + 509329 = 509442
149 + 509293 = 509442
179 + 509263 = 509442

Showing the first eight; more decompositions exist.
