Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509436, here are decompositions:

7 + 509429 = 509436
19 + 509417 = 509436
23 + 509413 = 509436
43 + 509393 = 509436
47 + 509389 = 509436
73 + 509363 = 509436
107 + 509329 = 509436
139 + 509297 = 509436

Showing the first eight; more decompositions exist.
