Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961840, here are decompositions:

23 + 961817 = 961840
29 + 961811 = 961840
71 + 961769 = 961840
83 + 961757 = 961840
101 + 961739 = 961840
107 + 961733 = 961840
137 + 961703 = 961840
149 + 961691 = 961840

Showing the first eight; more decompositions exist.
