Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639952, here are decompositions:

29 + 8639923 = 8639952
31 + 8639921 = 8639952
43 + 8639909 = 8639952
53 + 8639899 = 8639952
89 + 8639863 = 8639952
103 + 8639849 = 8639952
149 + 8639803 = 8639952
173 + 8639779 = 8639952

Showing the first eight; more decompositions exist.
