Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669904, here are decompositions:
- 7 + 8669897 = 8669904
- 11 + 8669893 = 8669904
- 43 + 8669861 = 8669904
- 73 + 8669831 = 8669904
- 83 + 8669821 = 8669904
- 127 + 8669777 = 8669904
- 137 + 8669767 = 8669904
- 233 + 8669671 = 8669904
Showing the first eight; more decompositions exist.
