Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961908, here are decompositions:

29 + 961879 = 961908
37 + 961871 = 961908
47 + 961861 = 961908
61 + 961847 = 961908
67 + 961841 = 961908
97 + 961811 = 961908
131 + 961777 = 961908
139 + 961769 = 961908

Showing the first eight; more decompositions exist.
