Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521046, here are decompositions:

5 + 521041 = 521046
7 + 521039 = 521046
23 + 521023 = 521046
37 + 521009 = 521046
79 + 520967 = 521046
83 + 520963 = 521046
89 + 520957 = 521046
103 + 520943 = 521046

Showing the first eight; more decompositions exist.
