Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981676, here are decompositions:

23 + 981653 = 981676
53 + 981623 = 981676
89 + 981587 = 981676
107 + 981569 = 981676
149 + 981527 = 981676
233 + 981443 = 981676
239 + 981437 = 981676
257 + 981419 = 981676

Showing the first eight; more decompositions exist.
