Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505880, here are decompositions:

3 + 505877 = 505880
13 + 505867 = 505880
61 + 505819 = 505880
103 + 505777 = 505880
211 + 505669 = 505880
223 + 505657 = 505880
241 + 505639 = 505880
307 + 505573 = 505880

Showing the first eight; more decompositions exist.
