Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700080, here are decompositions:

43 + 8700037 = 8700080
61 + 8700019 = 8700080
73 + 8700007 = 8700080
79 + 8700001 = 8700080
127 + 8699953 = 8700080
157 + 8699923 = 8700080
163 + 8699917 = 8700080
223 + 8699857 = 8700080

Showing the first eight; more decompositions exist.
