Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521146, here are decompositions:

83 + 521063 = 521146
107 + 521039 = 521146
137 + 521009 = 521146
179 + 520967 = 521146
233 + 520913 = 521146
257 + 520889 = 521146
293 + 520853 = 521146
359 + 520787 = 521146

Showing the first eight; more decompositions exist.
