Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649882, here are decompositions:

11 + 8649871 = 8649882
13 + 8649869 = 8649882
29 + 8649853 = 8649882
79 + 8649803 = 8649882
89 + 8649793 = 8649882
179 + 8649703 = 8649882
191 + 8649691 = 8649882
193 + 8649689 = 8649882

Showing the first eight; more decompositions exist.
