Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961100, here are decompositions:

3 + 961097 = 961100
13 + 961087 = 961100
31 + 961069 = 961100
37 + 961063 = 961100
67 + 961033 = 961100
79 + 961021 = 961100
97 + 961003 = 961100
109 + 960991 = 961100

Showing the first eight; more decompositions exist.
