Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669814, here are decompositions:

37 + 8669777 = 8669814
47 + 8669767 = 8669814
113 + 8669701 = 8669814
157 + 8669657 = 8669814
163 + 8669651 = 8669814
191 + 8669623 = 8669814
193 + 8669621 = 8669814
271 + 8669543 = 8669814

Showing the first eight; more decompositions exist.
