Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645104, here are decompositions:

23 + 8645081 = 8645104
113 + 8644991 = 8645104
191 + 8644913 = 8645104
353 + 8644751 = 8645104
401 + 8644703 = 8645104
443 + 8644661 = 8645104
593 + 8644511 = 8645104
647 + 8644457 = 8645104

Showing the first eight; more decompositions exist.
