Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640310, here are decompositions:

23 + 8640287 = 8640310
47 + 8640263 = 8640310
59 + 8640251 = 8640310
89 + 8640221 = 8640310
113 + 8640197 = 8640310
149 + 8640161 = 8640310
251 + 8640059 = 8640310
293 + 8640017 = 8640310

Showing the first eight; more decompositions exist.
