Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607972, here are decompositions:

29 + 8607943 = 8607972
59 + 8607913 = 8607972
71 + 8607901 = 8607972
89 + 8607883 = 8607972
101 + 8607871 = 8607972
151 + 8607821 = 8607972
223 + 8607749 = 8607972
239 + 8607733 = 8607972

Showing the first eight; more decompositions exist.
