Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617080, here are decompositions:

7 + 8617073 = 8617080
79 + 8617001 = 8617080
83 + 8616997 = 8617080
89 + 8616991 = 8617080
163 + 8616917 = 8617080
167 + 8616913 = 8617080
179 + 8616901 = 8617080
193 + 8616887 = 8617080

Showing the first eight; more decompositions exist.
