Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521252, here are decompositions:

73 + 521179 = 521252
79 + 521173 = 521252
211 + 521041 = 521252
229 + 521023 = 521252
271 + 520981 = 521252
283 + 520969 = 521252
331 + 520921 = 521252
439 + 520813 = 521252

Showing the first eight; more decompositions exist.
