Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642476, here are decompositions:

23 + 8642453 = 8642476
47 + 8642429 = 8642476
173 + 8642303 = 8642476
239 + 8642237 = 8642476
317 + 8642159 = 8642476
419 + 8642057 = 8642476
443 + 8642033 = 8642476
449 + 8642027 = 8642476

Showing the first eight; more decompositions exist.
