Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981466, here are decompositions:

23 + 981443 = 981466
29 + 981437 = 981466
47 + 981419 = 981466
89 + 981377 = 981466
179 + 981287 = 981466
257 + 981209 = 981466
293 + 981173 = 981466
389 + 981077 = 981466

Showing the first eight; more decompositions exist.
