Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515650, here are decompositions:

11 + 515639 = 515650
29 + 515621 = 515650
53 + 515597 = 515650
71 + 515579 = 515650
131 + 515519 = 515650
173 + 515477 = 515650
269 + 515381 = 515650
281 + 515369 = 515650

Showing the first eight; more decompositions exist.
