Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509378, here are decompositions:

19 + 509359 = 509378
61 + 509317 = 509378
97 + 509281 = 509378
139 + 509239 = 509378
151 + 509227 = 509378
157 + 509221 = 509378
229 + 509149 = 509378
241 + 509137 = 509378

Showing the first eight; more decompositions exist.
