Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644256, here are decompositions:

3 + 8644253 = 8644256
13 + 8644243 = 8644256
43 + 8644213 = 8644256
109 + 8644147 = 8644256
199 + 8644057 = 8644256
337 + 8643919 = 8644256
367 + 8643889 = 8644256
499 + 8643757 = 8644256

Showing the first eight; more decompositions exist.
