Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642004, here are decompositions:

13 + 8641991 = 8642004
17 + 8641987 = 8642004
47 + 8641957 = 8642004
113 + 8641891 = 8642004
131 + 8641873 = 8642004
197 + 8641807 = 8642004
223 + 8641781 = 8642004
257 + 8641747 = 8642004

Showing the first eight; more decompositions exist.
