Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648868, here are decompositions:

5 + 8648863 = 8648868
29 + 8648839 = 8648868
31 + 8648837 = 8648868
37 + 8648831 = 8648868
71 + 8648797 = 8648868
89 + 8648779 = 8648868
127 + 8648741 = 8648868
131 + 8648737 = 8648868

Showing the first eight; more decompositions exist.
