Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981248, here are decompositions:

7 + 981241 = 981248
61 + 981187 = 981248
97 + 981151 = 981248
109 + 981139 = 981248
157 + 981091 = 981248
181 + 981067 = 981248
199 + 981049 = 981248
211 + 981037 = 981248

Showing the first eight; more decompositions exist.
