Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722918, here are decompositions:

5 + 8722913 = 8722918
41 + 8722877 = 8722918
59 + 8722859 = 8722918
89 + 8722829 = 8722918
179 + 8722739 = 8722918
257 + 8722661 = 8722918
311 + 8722607 = 8722918
401 + 8722517 = 8722918

Showing the first eight; more decompositions exist.
