Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669172, here are decompositions:

13 + 8669159 = 8669172
59 + 8669113 = 8669172
89 + 8669083 = 8669172
101 + 8669071 = 8669172
131 + 8669041 = 8669172
179 + 8668993 = 8669172
199 + 8668973 = 8669172
271 + 8668901 = 8669172

Showing the first eight; more decompositions exist.
