Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648988, here are decompositions:

59 + 8648929 = 8648988
67 + 8648921 = 8648988
107 + 8648881 = 8648988
109 + 8648879 = 8648988
149 + 8648839 = 8648988
151 + 8648837 = 8648988
157 + 8648831 = 8648988
191 + 8648797 = 8648988

Showing the first eight; more decompositions exist.
