Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669400, here are decompositions:
- 7 + 8669393 = 8669400
- 11 + 8669389 = 8669400
- 59 + 8669341 = 8669400
- 67 + 8669333 = 8669400
- 71 + 8669329 = 8669400
- 83 + 8669317 = 8669400
- 107 + 8669293 = 8669400
- 149 + 8669251 = 8669400
Showing the first eight; more decompositions exist.
