Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515674, here are decompositions:

11 + 515663 = 515674
23 + 515651 = 515674
53 + 515621 = 515674
167 + 515507 = 515674
197 + 515477 = 515674
293 + 515381 = 515674
317 + 515357 = 515674
443 + 515231 = 515674

Showing the first eight; more decompositions exist.
