Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521970, here are decompositions:

41 + 521929 = 521970
47 + 521923 = 521970
67 + 521903 = 521970
73 + 521897 = 521970
83 + 521887 = 521970
89 + 521881 = 521970
101 + 521869 = 521970
109 + 521861 = 521970

Showing the first eight; more decompositions exist.
