Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981700, here are decompositions:

3 + 981697 = 981700
17 + 981683 = 981700
47 + 981653 = 981700
101 + 981599 = 981700
113 + 981587 = 981700
131 + 981569 = 981700
173 + 981527 = 981700
227 + 981473 = 981700

Showing the first eight; more decompositions exist.
