Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509222, here are decompositions:

19 + 509203 = 509222
73 + 509149 = 509222
151 + 509071 = 509222
199 + 509023 = 509222
271 + 508951 = 509222
313 + 508909 = 509222
433 + 508789 = 509222
601 + 508621 = 509222

Showing the first eight; more decompositions exist.
