Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521076, here are decompositions:

13 + 521063 = 521076
29 + 521047 = 521076
37 + 521039 = 521076
53 + 521023 = 521076
67 + 521009 = 521076
107 + 520969 = 521076
109 + 520967 = 521076
113 + 520963 = 521076

Showing the first eight; more decompositions exist.
