Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008940, here are decompositions:

3 + 1008937 = 1008940
17 + 1008923 = 1008940
29 + 1008911 = 1008940
83 + 1008857 = 1008940
89 + 1008851 = 1008940
131 + 1008809 = 1008940
167 + 1008773 = 1008940
197 + 1008743 = 1008940

Showing the first eight; more decompositions exist.
