Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515262, here are decompositions:

29 + 515233 = 515262
31 + 515231 = 515262
71 + 515191 = 515262
89 + 515173 = 515262
109 + 515153 = 515262
113 + 515149 = 515262
151 + 515111 = 515262
173 + 515089 = 515262

Showing the first eight; more decompositions exist.
