Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669790, here are decompositions:

13 + 8669777 = 8669790
23 + 8669767 = 8669790
89 + 8669701 = 8669790
139 + 8669651 = 8669790
163 + 8669627 = 8669790
167 + 8669623 = 8669790
179 + 8669611 = 8669790
197 + 8669593 = 8669790

Showing the first eight; more decompositions exist.
