Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981486, here are decompositions:

5 + 981481 = 981486
13 + 981473 = 981486
19 + 981467 = 981486
43 + 981443 = 981486
47 + 981439 = 981486
67 + 981419 = 981486
89 + 981397 = 981486
109 + 981377 = 981486

Showing the first eight; more decompositions exist.
