Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 957840, here are decompositions:

17 + 957823 = 957840
19 + 957821 = 957840
29 + 957811 = 957840
67 + 957773 = 957840
71 + 957769 = 957840
89 + 957751 = 957840
109 + 957731 = 957840
131 + 957709 = 957840

Showing the first eight; more decompositions exist.
