Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640308, here are decompositions:

67 + 8640241 = 8640308
97 + 8640211 = 8640308
139 + 8640169 = 8640308
199 + 8640109 = 8640308
307 + 8640001 = 8640308
331 + 8639977 = 8640308
409 + 8639899 = 8640308
499 + 8639809 = 8640308

Showing the first eight; more decompositions exist.
