Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521534, here are decompositions:

7 + 521527 = 521534
31 + 521503 = 521534
37 + 521497 = 521534
43 + 521491 = 521534
157 + 521377 = 521534
283 + 521251 = 521534
367 + 521167 = 521534
373 + 521161 = 521534

Showing the first eight; more decompositions exist.
