Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521206, here are decompositions:

5 + 521201 = 521206
29 + 521177 = 521206
53 + 521153 = 521206
167 + 521039 = 521206
197 + 521009 = 521206
239 + 520967 = 521206
263 + 520943 = 521206
293 + 520913 = 521206

Showing the first eight; more decompositions exist.
