Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521104, here are decompositions:

41 + 521063 = 521104
53 + 521051 = 521104
83 + 521021 = 521104
137 + 520967 = 521104
191 + 520913 = 521104
251 + 520853 = 521104
263 + 520841 = 521104
317 + 520787 = 521104

Showing the first eight; more decompositions exist.
