Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981708, here are decompositions:

5 + 981703 = 981708
11 + 981697 = 981708
17 + 981691 = 981708
71 + 981637 = 981708
107 + 981601 = 981708
109 + 981599 = 981708
131 + 981577 = 981708
139 + 981569 = 981708

Showing the first eight; more decompositions exist.
