Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521236, here are decompositions:

5 + 521231 = 521236
59 + 521177 = 521236
83 + 521153 = 521236
173 + 521063 = 521236
197 + 521039 = 521236
227 + 521009 = 521236
269 + 520967 = 521236
293 + 520943 = 521236

Showing the first eight; more decompositions exist.
