Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640164, here are decompositions:

3 + 8640161 = 8640164
31 + 8640133 = 8640164
151 + 8640013 = 8640164
163 + 8640001 = 8640164
241 + 8639923 = 8640164
367 + 8639797 = 8640164
601 + 8639563 = 8640164
613 + 8639551 = 8640164

Showing the first eight; more decompositions exist.
