Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505550, here are decompositions:

13 + 505537 = 505550
37 + 505513 = 505550
103 + 505447 = 505550
139 + 505411 = 505550
151 + 505399 = 505550
181 + 505369 = 505550
193 + 505357 = 505550
211 + 505339 = 505550

Showing the first eight; more decompositions exist.
