Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521772, here are decompositions:

5 + 521767 = 521772
19 + 521753 = 521772
23 + 521749 = 521772
29 + 521743 = 521772
79 + 521693 = 521772
101 + 521671 = 521772
103 + 521669 = 521772
113 + 521659 = 521772

Showing the first eight; more decompositions exist.
