Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505340, here are decompositions:

13 + 505327 = 505340
19 + 505321 = 505340
61 + 505279 = 505340
103 + 505237 = 505340
109 + 505231 = 505340
127 + 505213 = 505340
139 + 505201 = 505340
181 + 505159 = 505340

Showing the first eight; more decompositions exist.
