Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505028, here are decompositions:

37 + 504991 = 505028
61 + 504967 = 505028
127 + 504901 = 505028
151 + 504877 = 505028
157 + 504871 = 505028
211 + 504817 = 505028
229 + 504799 = 505028
241 + 504787 = 505028

Showing the first eight; more decompositions exist.
