Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981336, here are decompositions:

17 + 981319 = 981336
47 + 981289 = 981336
53 + 981283 = 981336
73 + 981263 = 981336
127 + 981209 = 981336
137 + 981199 = 981336
149 + 981187 = 981336
163 + 981173 = 981336

Showing the first eight; more decompositions exist.
