Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9384, here are decompositions:
- 7 + 9377 = 9384
- 13 + 9371 = 9384
- 41 + 9343 = 9384
- 43 + 9341 = 9384
- 47 + 9337 = 9384
- 61 + 9323 = 9384
- 73 + 9311 = 9384
- 101 + 9283 = 9384
Showing the first eight; more decompositions exist.
