Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509372, here are decompositions:

13 + 509359 = 509372
43 + 509329 = 509372
79 + 509293 = 509372
109 + 509263 = 509372
151 + 509221 = 509372
223 + 509149 = 509372
271 + 509101 = 509372
349 + 509023 = 509372

Showing the first eight; more decompositions exist.
