Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981184, here are decompositions:

11 + 981173 = 981184
47 + 981137 = 981184
107 + 981077 = 981184
167 + 981017 = 981184
173 + 981011 = 981184
227 + 980957 = 981184
263 + 980921 = 981184
353 + 980831 = 981184

Showing the first eight; more decompositions exist.
