Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658880, here are decompositions:

3 + 8658877 = 8658880
11 + 8658869 = 8658880
107 + 8658773 = 8658880
227 + 8658653 = 8658880
311 + 8658569 = 8658880
353 + 8658527 = 8658880
449 + 8658431 = 8658880
467 + 8658413 = 8658880

Showing the first eight; more decompositions exist.
