Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515836, here are decompositions:

23 + 515813 = 515836
53 + 515783 = 515836
59 + 515777 = 515836
149 + 515687 = 515836
173 + 515663 = 515836
197 + 515639 = 515836
239 + 515597 = 515836
257 + 515579 = 515836

Showing the first eight; more decompositions exist.
