Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642294, here are decompositions:

13 + 8642281 = 8642294
97 + 8642197 = 8642294
307 + 8641987 = 8642294
337 + 8641957 = 8642294
421 + 8641873 = 8642294
487 + 8641807 = 8642294
547 + 8641747 = 8642294
643 + 8641651 = 8642294

Showing the first eight; more decompositions exist.
