Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961900, here are decompositions:

29 + 961871 = 961900
47 + 961853 = 961900
53 + 961847 = 961900
59 + 961841 = 961900
83 + 961817 = 961900
89 + 961811 = 961900
131 + 961769 = 961900
167 + 961733 = 961900

Showing the first eight; more decompositions exist.
