Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700920, here are decompositions:

103 + 8700817 = 8700920
127 + 8700793 = 8700920
199 + 8700721 = 8700920
211 + 8700709 = 8700920
223 + 8700697 = 8700920
271 + 8700649 = 8700920
331 + 8700589 = 8700920
373 + 8700547 = 8700920

Showing the first eight; more decompositions exist.
