Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521976, here are decompositions:

47 + 521929 = 521976
53 + 521923 = 521976
73 + 521903 = 521976
79 + 521897 = 521976
89 + 521887 = 521976
97 + 521879 = 521976
107 + 521869 = 521976
157 + 521819 = 521976

Showing the first eight; more decompositions exist.
