Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521194, here are decompositions:

17 + 521177 = 521194
41 + 521153 = 521194
131 + 521063 = 521194
173 + 521021 = 521194
227 + 520967 = 521194
251 + 520943 = 521194
281 + 520913 = 521194
353 + 520841 = 521194

Showing the first eight; more decompositions exist.
