Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981610, here are decompositions:

11 + 981599 = 981610
23 + 981587 = 981610
41 + 981569 = 981610
83 + 981527 = 981610
137 + 981473 = 981610
167 + 981443 = 981610
173 + 981437 = 981610
191 + 981419 = 981610

Showing the first eight; more decompositions exist.
