Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641926, here are decompositions:

17 + 8641909 = 8641926
43 + 8641883 = 8641926
53 + 8641873 = 8641926
107 + 8641819 = 8641926
109 + 8641817 = 8641926
179 + 8641747 = 8641926
193 + 8641733 = 8641926
229 + 8641697 = 8641926

Showing the first eight; more decompositions exist.
