Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521234, here are decompositions:

3 + 521231 = 521234
61 + 521173 = 521234
67 + 521167 = 521234
73 + 521161 = 521234
97 + 521137 = 521234
127 + 521107 = 521234
193 + 521041 = 521234
211 + 521023 = 521234

Showing the first eight; more decompositions exist.
