Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981706, here are decompositions:

3 + 981703 = 981706
23 + 981683 = 981706
53 + 981653 = 981706
83 + 981623 = 981706
107 + 981599 = 981706
137 + 981569 = 981706
179 + 981527 = 981706
233 + 981473 = 981706

Showing the first eight; more decompositions exist.
