Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646382, here are decompositions:

5 + 8646377 = 8646382
53 + 8646329 = 8646382
83 + 8646299 = 8646382
89 + 8646293 = 8646382
113 + 8646269 = 8646382
149 + 8646233 = 8646382
263 + 8646119 = 8646382
401 + 8645981 = 8646382

Showing the first eight; more decompositions exist.
