Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509888, here are decompositions:

151 + 509737 = 509888
157 + 509731 = 509888
199 + 509689 = 509888
229 + 509659 = 509888
241 + 509647 = 509888
307 + 509581 = 509888
331 + 509557 = 509888
367 + 509521 = 509888

Showing the first eight; more decompositions exist.
