Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725822, here are decompositions:

5 + 8725817 = 8725822
23 + 8725799 = 8725822
89 + 8725733 = 8725822
179 + 8725643 = 8725822
191 + 8725631 = 8725822
251 + 8725571 = 8725822
311 + 8725511 = 8725822
359 + 8725463 = 8725822

Showing the first eight; more decompositions exist.
