Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669140, here are decompositions:

17 + 8669123 = 8669140
23 + 8669117 = 8669140
113 + 8669027 = 8669140
167 + 8668973 = 8669140
173 + 8668967 = 8669140
239 + 8668901 = 8669140
251 + 8668889 = 8669140
401 + 8668739 = 8669140

Showing the first eight; more decompositions exist.
