Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509402, here are decompositions:

13 + 509389 = 509402
43 + 509359 = 509402
73 + 509329 = 509402
109 + 509293 = 509402
139 + 509263 = 509402
163 + 509239 = 509402
181 + 509221 = 509402
199 + 509203 = 509402

Showing the first eight; more decompositions exist.
