Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515082, here are decompositions:

41 + 515041 = 515082
149 + 514933 = 515082
179 + 514903 = 515082
193 + 514889 = 515082
223 + 514859 = 515082
229 + 514853 = 515082
241 + 514841 = 515082
251 + 514831 = 515082

Showing the first eight; more decompositions exist.
