Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521996, here are decompositions:

3 + 521993 = 521996
67 + 521929 = 521996
73 + 521923 = 521996
109 + 521887 = 521996
127 + 521869 = 521996
229 + 521767 = 521996
337 + 521659 = 521996
439 + 521557 = 521996

Showing the first eight; more decompositions exist.
