Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981406, here are decompositions:

29 + 981377 = 981406
197 + 981209 = 981406
233 + 981173 = 981406
269 + 981137 = 981406
383 + 981023 = 981406
389 + 981017 = 981406
443 + 980963 = 981406
449 + 980957 = 981406

Showing the first eight; more decompositions exist.
