Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505580, here are decompositions:

7 + 505573 = 505580
43 + 505537 = 505580
67 + 505513 = 505580
79 + 505501 = 505580
151 + 505429 = 505580
181 + 505399 = 505580
211 + 505369 = 505580
223 + 505357 = 505580

Showing the first eight; more decompositions exist.
