Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669190, here are decompositions:

11 + 8669179 = 8669190
31 + 8669159 = 8669190
67 + 8669123 = 8669190
73 + 8669117 = 8669190
83 + 8669107 = 8669190
107 + 8669083 = 8669190
149 + 8669041 = 8669190
163 + 8669027 = 8669190

Showing the first eight; more decompositions exist.
