Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644260, here are decompositions:

7 + 8644253 = 8644260
17 + 8644243 = 8644260
29 + 8644231 = 8644260
47 + 8644213 = 8644260
73 + 8644187 = 8644260
89 + 8644171 = 8644260
103 + 8644157 = 8644260
113 + 8644147 = 8644260

Showing the first eight; more decompositions exist.
