Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521462, here are decompositions:

61 + 521401 = 521462
103 + 521359 = 521462
163 + 521299 = 521462
181 + 521281 = 521462
211 + 521251 = 521462
283 + 521179 = 521462
421 + 521041 = 521462
439 + 521023 = 521462

Showing the first eight; more decompositions exist.
