Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642286, here are decompositions:

5 + 8642281 = 8642286
89 + 8642197 = 8642286
97 + 8642189 = 8642286
113 + 8642173 = 8642286
127 + 8642159 = 8642286
139 + 8642147 = 8642286
167 + 8642119 = 8642286
179 + 8642107 = 8642286

Showing the first eight; more decompositions exist.
