Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700122, here are decompositions:

43 + 8700079 = 8700122
103 + 8700019 = 8700122
163 + 8699959 = 8700122
199 + 8699923 = 8700122
229 + 8699893 = 8700122
271 + 8699851 = 8700122
463 + 8699659 = 8700122
709 + 8699413 = 8700122

Showing the first eight; more decompositions exist.
