Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521294, here are decompositions:

13 + 521281 = 521294
43 + 521251 = 521294
127 + 521167 = 521294
157 + 521137 = 521294
271 + 521023 = 521294
313 + 520981 = 521294
331 + 520963 = 521294
337 + 520957 = 521294

Showing the first eight; more decompositions exist.
