Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515022, here are decompositions:

73 + 514949 = 515022
83 + 514939 = 515022
89 + 514933 = 515022
149 + 514873 = 515022
163 + 514859 = 515022
181 + 514841 = 515022
191 + 514831 = 515022
199 + 514823 = 515022

Showing the first eight; more decompositions exist.
