Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505480, here are decompositions:

11 + 505469 = 505480
71 + 505409 = 505480
113 + 505367 = 505480
167 + 505313 = 505480
179 + 505301 = 505480
197 + 505283 = 505480
293 + 505187 = 505480
383 + 505097 = 505480

Showing the first eight; more decompositions exist.
