Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521944, here are decompositions:

41 + 521903 = 521944
47 + 521897 = 521944
83 + 521861 = 521944
113 + 521831 = 521944
131 + 521813 = 521944
167 + 521777 = 521944
191 + 521753 = 521944
251 + 521693 = 521944

Showing the first eight; more decompositions exist.
