Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649922, here are decompositions:

11 + 8649911 = 8649922
41 + 8649881 = 8649922
53 + 8649869 = 8649922
131 + 8649791 = 8649922
233 + 8649689 = 8649922
251 + 8649671 = 8649922
293 + 8649629 = 8649922
311 + 8649611 = 8649922

Showing the first eight; more decompositions exist.
