Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621926, here are decompositions:

29 + 8621897 = 8621926
59 + 8621867 = 8621926
83 + 8621843 = 8621926
107 + 8621819 = 8621926
179 + 8621747 = 8621926
233 + 8621693 = 8621926
317 + 8621609 = 8621926
449 + 8621477 = 8621926

Showing the first eight; more decompositions exist.
