Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521176, here are decompositions:

3 + 521173 = 521176
23 + 521153 = 521176
113 + 521063 = 521176
137 + 521039 = 521176
167 + 521009 = 521176
233 + 520943 = 521176
263 + 520913 = 521176
389 + 520787 = 521176

Showing the first eight; more decompositions exist.
