Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658924, here are decompositions:

5 + 8658919 = 8658924
13 + 8658911 = 8658924
31 + 8658893 = 8658924
37 + 8658887 = 8658924
47 + 8658877 = 8658924
151 + 8658773 = 8658924
167 + 8658757 = 8658924
227 + 8658697 = 8658924

Showing the first eight; more decompositions exist.
