Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521966, here are decompositions:

37 + 521929 = 521966
43 + 521923 = 521966
79 + 521887 = 521966
97 + 521869 = 521966
157 + 521809 = 521966
199 + 521767 = 521966
223 + 521743 = 521966
307 + 521659 = 521966

Showing the first eight; more decompositions exist.
