Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644268, here are decompositions:

7 + 8644261 = 8644268
37 + 8644231 = 8644268
97 + 8644171 = 8644268
211 + 8644057 = 8644268
271 + 8643997 = 8644268
277 + 8643991 = 8644268
349 + 8643919 = 8644268
379 + 8643889 = 8644268

Showing the first eight; more decompositions exist.
