Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981460, here are decompositions:

17 + 981443 = 981460
23 + 981437 = 981460
41 + 981419 = 981460
83 + 981377 = 981460
149 + 981311 = 981460
173 + 981287 = 981460
197 + 981263 = 981460
239 + 981221 = 981460

Showing the first eight; more decompositions exist.
