Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605992, here are decompositions:

29 + 8605963 = 8605992
53 + 8605939 = 8605992
61 + 8605931 = 8605992
79 + 8605913 = 8605992
139 + 8605853 = 8605992
149 + 8605843 = 8605992
163 + 8605829 = 8605992
179 + 8605813 = 8605992

Showing the first eight; more decompositions exist.
