Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605942, here are decompositions:

3 + 8605939 = 8605942
11 + 8605931 = 8605942
29 + 8605913 = 8605942
71 + 8605871 = 8605942
89 + 8605853 = 8605942
113 + 8605829 = 8605942
131 + 8605811 = 8605942
251 + 8605691 = 8605942

Showing the first eight; more decompositions exist.
