Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521984, here are decompositions:

3 + 521981 = 521984
61 + 521923 = 521984
97 + 521887 = 521984
103 + 521881 = 521984
193 + 521791 = 521984
241 + 521743 = 521984
277 + 521707 = 521984
313 + 521671 = 521984

Showing the first eight; more decompositions exist.
