Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9444, here are decompositions:
- 5 + 9439 = 9444
- 7 + 9437 = 9444
- 11 + 9433 = 9444
- 13 + 9431 = 9444
- 23 + 9421 = 9444
- 31 + 9413 = 9444
- 41 + 9403 = 9444
- 47 + 9397 = 9444
Showing the first eight; more decompositions exist.
