Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641944, here are decompositions:

53 + 8641891 = 8641944
61 + 8641883 = 8641944
71 + 8641873 = 8641944
127 + 8641817 = 8641944
137 + 8641807 = 8641944
163 + 8641781 = 8641944
197 + 8641747 = 8641944
211 + 8641733 = 8641944

Showing the first eight; more decompositions exist.
