Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521276, here are decompositions:

97 + 521179 = 521276
103 + 521173 = 521276
109 + 521167 = 521276
139 + 521137 = 521276
157 + 521119 = 521276
229 + 521047 = 521276
307 + 520969 = 521276
313 + 520963 = 521276

Showing the first eight; more decompositions exist.
