Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521326, here are decompositions:

17 + 521309 = 521326
59 + 521267 = 521326
83 + 521243 = 521326
149 + 521177 = 521326
173 + 521153 = 521326
263 + 521063 = 521326
317 + 521009 = 521326
359 + 520967 = 521326

Showing the first eight; more decompositions exist.
