Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981344, here are decompositions:

43 + 981301 = 981344
61 + 981283 = 981344
73 + 981271 = 981344
103 + 981241 = 981344
157 + 981187 = 981344
193 + 981151 = 981344
211 + 981133 = 981344
271 + 981073 = 981344

Showing the first eight; more decompositions exist.
