Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644274, here are decompositions:

13 + 8644261 = 8644274
31 + 8644243 = 8644274
43 + 8644231 = 8644274
61 + 8644213 = 8644274
103 + 8644171 = 8644274
127 + 8644147 = 8644274
151 + 8644123 = 8644274
193 + 8644081 = 8644274

Showing the first eight; more decompositions exist.
