Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521116, here are decompositions:

53 + 521063 = 521116
107 + 521009 = 521116
149 + 520967 = 521116
173 + 520943 = 521116
227 + 520889 = 521116
263 + 520853 = 521116
353 + 520763 = 521116
467 + 520649 = 521116

Showing the first eight; more decompositions exist.
