Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669642, here are decompositions:
- 13 + 8669629 = 8669642
- 19 + 8669623 = 8669642
- 31 + 8669611 = 8669642
- 199 + 8669443 = 8669642
- 313 + 8669329 = 8669642
- 349 + 8669293 = 8669642
- 409 + 8669233 = 8669642
- 463 + 8669179 = 8669642
Showing the first eight; more decompositions exist.
