Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521196, here are decompositions:

17 + 521179 = 521196
19 + 521177 = 521196
23 + 521173 = 521196
29 + 521167 = 521196
43 + 521153 = 521196
59 + 521137 = 521196
89 + 521107 = 521196
149 + 521047 = 521196

Showing the first eight; more decompositions exist.
