Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981306, here are decompositions:

5 + 981301 = 981306
17 + 981289 = 981306
19 + 981287 = 981306
23 + 981283 = 981306
43 + 981263 = 981306
97 + 981209 = 981306
107 + 981199 = 981306
167 + 981139 = 981306

Showing the first eight; more decompositions exist.
