Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628948, here are decompositions:

11 + 8628937 = 8628948
59 + 8628889 = 8628948
89 + 8628859 = 8628948
101 + 8628847 = 8628948
137 + 8628811 = 8628948
149 + 8628799 = 8628948
157 + 8628791 = 8628948
197 + 8628751 = 8628948

Showing the first eight; more decompositions exist.
