Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981456, here are decompositions:

5 + 981451 = 981456
13 + 981443 = 981456
17 + 981439 = 981456
19 + 981437 = 981456
37 + 981419 = 981456
59 + 981397 = 981456
79 + 981377 = 981456
83 + 981373 = 981456

Showing the first eight; more decompositions exist.
