Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521422, here are decompositions:

23 + 521399 = 521422
29 + 521393 = 521422
53 + 521369 = 521422
59 + 521363 = 521422
113 + 521309 = 521422
179 + 521243 = 521422
191 + 521231 = 521422
269 + 521153 = 521422

Showing the first eight; more decompositions exist.
