Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981338, here are decompositions:

19 + 981319 = 981338
37 + 981301 = 981338
67 + 981271 = 981338
97 + 981241 = 981338
139 + 981199 = 981338
151 + 981187 = 981338
199 + 981139 = 981338
271 + 981067 = 981338

Showing the first eight; more decompositions exist.
