Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981314, here are decompositions:

3 + 981311 = 981314
13 + 981301 = 981314
31 + 981283 = 981314
43 + 981271 = 981314
73 + 981241 = 981314
127 + 981187 = 981314
163 + 981151 = 981314
181 + 981133 = 981314

Showing the first eight; more decompositions exist.
