Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509418, here are decompositions:

5 + 509413 = 509418
29 + 509389 = 509418
59 + 509359 = 509418
89 + 509329 = 509418
101 + 509317 = 509418
131 + 509287 = 509418
137 + 509281 = 509418
179 + 509239 = 509418

Showing the first eight; more decompositions exist.
