Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9442, here are decompositions:
- 3 + 9439 = 9442
- 5 + 9437 = 9442
- 11 + 9431 = 9442
- 23 + 9419 = 9442
- 29 + 9413 = 9442
- 71 + 9371 = 9442
- 101 + 9341 = 9442
- 131 + 9311 = 9442
Showing the first eight; more decompositions exist.
