Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521514, here are decompositions:

11 + 521503 = 521514
17 + 521497 = 521514
23 + 521491 = 521514
31 + 521483 = 521514
43 + 521471 = 521514
67 + 521447 = 521514
113 + 521401 = 521514
137 + 521377 = 521514

Showing the first eight; more decompositions exist.
