Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642376, here are decompositions:

47 + 8642329 = 8642376
73 + 8642303 = 8642376
139 + 8642237 = 8642376
179 + 8642197 = 8642376
229 + 8642147 = 8642376
257 + 8642119 = 8642376
269 + 8642107 = 8642376
277 + 8642099 = 8642376

Showing the first eight; more decompositions exist.
