Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640070, here are decompositions:

11 + 8640059 = 8640070
53 + 8640017 = 8640070
83 + 8639987 = 8640070
149 + 8639921 = 8640070
167 + 8639903 = 8640070
233 + 8639837 = 8640070
251 + 8639819 = 8640070
317 + 8639753 = 8640070

Showing the first eight; more decompositions exist.
