Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644100, here are decompositions:

19 + 8644081 = 8644100
43 + 8644057 = 8644100
103 + 8643997 = 8644100
109 + 8643991 = 8644100
181 + 8643919 = 8644100
211 + 8643889 = 8644100
313 + 8643787 = 8644100
379 + 8643721 = 8644100

Showing the first eight; more decompositions exist.
