Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978700, here are decompositions:

3 + 978697 = 978700
11 + 978689 = 978700
17 + 978683 = 978700
53 + 978647 = 978700
83 + 978617 = 978700
89 + 978611 = 978700
101 + 978599 = 978700
131 + 978569 = 978700

Showing the first eight; more decompositions exist.
