Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515302, here are decompositions:

23 + 515279 = 515302
71 + 515231 = 515302
149 + 515153 = 515302
191 + 515111 = 515302
353 + 514949 = 515302
443 + 514859 = 515302
449 + 514853 = 515302
461 + 514841 = 515302

Showing the first eight; more decompositions exist.
