Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515230, here are decompositions:

3 + 515227 = 515230
263 + 514967 = 515230
281 + 514949 = 515230
383 + 514847 = 515230
389 + 514841 = 515230
461 + 514769 = 515230
479 + 514751 = 515230
491 + 514739 = 515230

Showing the first eight; more decompositions exist.
