Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722948, here are decompositions:

71 + 8722877 = 8722948
89 + 8722859 = 8722948
107 + 8722841 = 8722948
149 + 8722799 = 8722948
191 + 8722757 = 8722948
317 + 8722631 = 8722948
431 + 8722517 = 8722948
449 + 8722499 = 8722948

Showing the first eight; more decompositions exist.
