Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521754, here are decompositions:

5 + 521749 = 521754
11 + 521743 = 521754
31 + 521723 = 521754
47 + 521707 = 521754
61 + 521693 = 521754
83 + 521671 = 521754
97 + 521657 = 521754
113 + 521641 = 521754

Showing the first eight; more decompositions exist.
