Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722962, here are decompositions:

13 + 8722949 = 8722962
71 + 8722891 = 8722962
103 + 8722859 = 8722962
163 + 8722799 = 8722962
173 + 8722789 = 8722962
223 + 8722739 = 8722962
251 + 8722711 = 8722962
331 + 8722631 = 8722962

Showing the first eight; more decompositions exist.
