Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712942, here are decompositions:

11 + 8712931 = 8712942
23 + 8712919 = 8712942
79 + 8712863 = 8712942
83 + 8712859 = 8712942
149 + 8712793 = 8712942
163 + 8712779 = 8712942
181 + 8712761 = 8712942
191 + 8712751 = 8712942

Showing the first eight; more decompositions exist.
