Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725858, here are decompositions:

17 + 8725841 = 8725858
41 + 8725817 = 8725858
59 + 8725799 = 8725858
101 + 8725757 = 8725858
227 + 8725631 = 8725858
311 + 8725547 = 8725858
347 + 8725511 = 8725858
359 + 8725499 = 8725858

Showing the first eight; more decompositions exist.
