Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515562, here are decompositions:

23 + 515539 = 515562
43 + 515519 = 515562
181 + 515381 = 515562
191 + 515371 = 515562
193 + 515369 = 515562
211 + 515351 = 515562
239 + 515323 = 515562
251 + 515311 = 515562

Showing the first eight; more decompositions exist.
