Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521106, here are decompositions:

43 + 521063 = 521106
59 + 521047 = 521106
67 + 521039 = 521106
83 + 521023 = 521106
97 + 521009 = 521106
137 + 520969 = 521106
139 + 520967 = 521106
149 + 520957 = 521106

Showing the first eight; more decompositions exist.
