Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515204, here are decompositions:

13 + 515191 = 515204
31 + 515173 = 515204
61 + 515143 = 515204
163 + 515041 = 515204
271 + 514933 = 515204
331 + 514873 = 515204
337 + 514867 = 515204
373 + 514831 = 515204

Showing the first eight; more decompositions exist.
