Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607942, here are decompositions:

29 + 8607913 = 8607942
41 + 8607901 = 8607942
59 + 8607883 = 8607942
71 + 8607871 = 8607942
139 + 8607803 = 8607942
173 + 8607769 = 8607942
193 + 8607749 = 8607942
229 + 8607713 = 8607942

Showing the first eight; more decompositions exist.
