Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981448, here are decompositions:

5 + 981443 = 981448
11 + 981437 = 981448
29 + 981419 = 981448
71 + 981377 = 981448
137 + 981311 = 981448
227 + 981221 = 981448
239 + 981209 = 981448
311 + 981137 = 981448

Showing the first eight; more decompositions exist.
