Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761100, here are decompositions:

109 + 8760991 = 8761100
199 + 8760901 = 8761100
223 + 8760877 = 8761100
373 + 8760727 = 8761100
379 + 8760721 = 8761100
433 + 8760667 = 8761100
487 + 8760613 = 8761100
547 + 8760553 = 8761100

Showing the first eight; more decompositions exist.
