Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680880, here are decompositions:

67 + 8680813 = 8680880
79 + 8680801 = 8680880
127 + 8680753 = 8680880
139 + 8680741 = 8680880
157 + 8680723 = 8680880
163 + 8680717 = 8680880
181 + 8680699 = 8680880
211 + 8680669 = 8680880

Showing the first eight; more decompositions exist.
