Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521346, here are decompositions:

17 + 521329 = 521346
29 + 521317 = 521346
37 + 521309 = 521346
47 + 521299 = 521346
79 + 521267 = 521346
103 + 521243 = 521346
167 + 521179 = 521346
173 + 521173 = 521346

Showing the first eight; more decompositions exist.
