Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521960, here are decompositions:

31 + 521929 = 521960
37 + 521923 = 521960
73 + 521887 = 521960
79 + 521881 = 521960
151 + 521809 = 521960
193 + 521767 = 521960
211 + 521749 = 521960
379 + 521581 = 521960

Showing the first eight; more decompositions exist.
