Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521174, here are decompositions:

7 + 521167 = 521174
13 + 521161 = 521174
37 + 521137 = 521174
67 + 521107 = 521174
127 + 521047 = 521174
151 + 521023 = 521174
193 + 520981 = 521174
211 + 520963 = 521174

Showing the first eight; more decompositions exist.
