Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751660, here are decompositions:

31 + 8751629 = 8751660
41 + 8751619 = 8751660
61 + 8751599 = 8751660
67 + 8751593 = 8751660
83 + 8751577 = 8751660
97 + 8751563 = 8751660
103 + 8751557 = 8751660
157 + 8751503 = 8751660

Showing the first eight; more decompositions exist.
