Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645026, here are decompositions:

3 + 8645023 = 8645026
17 + 8645009 = 8645026
107 + 8644919 = 8645026
113 + 8644913 = 8645026
227 + 8644799 = 8645026
347 + 8644679 = 8645026
419 + 8644607 = 8645026
569 + 8644457 = 8645026

Showing the first eight; more decompositions exist.
