Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628888, here are decompositions:

5 + 8628883 = 8628888
29 + 8628859 = 8628888
31 + 8628857 = 8628888
41 + 8628847 = 8628888
89 + 8628799 = 8628888
97 + 8628791 = 8628888
101 + 8628787 = 8628888
109 + 8628779 = 8628888

Showing the first eight; more decompositions exist.
