Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640184, here are decompositions:

23 + 8640161 = 8640184
167 + 8640017 = 8640184
197 + 8639987 = 8640184
233 + 8639951 = 8640184
263 + 8639921 = 8640184
281 + 8639903 = 8640184
347 + 8639837 = 8640184
431 + 8639753 = 8640184

Showing the first eight; more decompositions exist.
