Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645382, here are decompositions:

23 + 8645359 = 8645382
29 + 8645353 = 8645382
41 + 8645341 = 8645382
89 + 8645293 = 8645382
101 + 8645281 = 8645382
113 + 8645269 = 8645382
139 + 8645243 = 8645382
241 + 8645141 = 8645382

Showing the first eight; more decompositions exist.
