Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521396, here are decompositions:

3 + 521393 = 521396
19 + 521377 = 521396
37 + 521359 = 521396
67 + 521329 = 521396
79 + 521317 = 521396
97 + 521299 = 521396
223 + 521173 = 521396
229 + 521167 = 521396

Showing the first eight; more decompositions exist.
