Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981272, here are decompositions:

31 + 981241 = 981272
73 + 981199 = 981272
139 + 981133 = 981272
181 + 981091 = 981272
199 + 981073 = 981272
211 + 981061 = 981272
223 + 981049 = 981272
373 + 980899 = 981272

Showing the first eight; more decompositions exist.
