Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515350, here are decompositions:

71 + 515279 = 515350
113 + 515237 = 515350
197 + 515153 = 515350
239 + 515111 = 515350
263 + 515087 = 515350
383 + 514967 = 515350
401 + 514949 = 515350
461 + 514889 = 515350

Showing the first eight; more decompositions exist.
