Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515526, here are decompositions:

7 + 515519 = 515526
19 + 515507 = 515526
97 + 515429 = 515526
149 + 515377 = 515526
157 + 515369 = 515526
233 + 515293 = 515526
293 + 515233 = 515526
353 + 515173 = 515526

Showing the first eight; more decompositions exist.
