Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981670, here are decompositions:

17 + 981653 = 981670
47 + 981623 = 981670
71 + 981599 = 981670
83 + 981587 = 981670
101 + 981569 = 981670
197 + 981473 = 981670
227 + 981443 = 981670
233 + 981437 = 981670

Showing the first eight; more decompositions exist.
