Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645344, here are decompositions:

3 + 8645341 = 8645344
17 + 8645327 = 8645344
83 + 8645261 = 8645344
101 + 8645243 = 8645344
107 + 8645237 = 8645344
263 + 8645081 = 8645344
353 + 8644991 = 8645344
431 + 8644913 = 8645344

Showing the first eight; more decompositions exist.
