Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640004, here are decompositions:

3 + 8640001 = 8640004
17 + 8639987 = 8640004
53 + 8639951 = 8640004
83 + 8639921 = 8640004
101 + 8639903 = 8640004
167 + 8639837 = 8640004
251 + 8639753 = 8640004
257 + 8639747 = 8640004

Showing the first eight; more decompositions exist.
