Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9408, here are decompositions:
- 5 + 9403 = 9408
- 11 + 9397 = 9408
- 17 + 9391 = 9408
- 31 + 9377 = 9408
- 37 + 9371 = 9408
- 59 + 9349 = 9408
- 67 + 9341 = 9408
- 71 + 9337 = 9408
Showing the first eight; more decompositions exist.
