Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981696, here are decompositions:

5 + 981691 = 981696
13 + 981683 = 981696
43 + 981653 = 981696
59 + 981637 = 981696
73 + 981623 = 981696
97 + 981599 = 981696
109 + 981587 = 981696
127 + 981569 = 981696

Showing the first eight; more decompositions exist.
