Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521662, here are decompositions:

3 + 521659 = 521662
5 + 521657 = 521662
59 + 521603 = 521662
179 + 521483 = 521662
191 + 521471 = 521662
233 + 521429 = 521662
263 + 521399 = 521662
269 + 521393 = 521662

Showing the first eight; more decompositions exist.
