Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4372, here are decompositions:
- 23 + 4349 = 4372
- 83 + 4289 = 4372
- 89 + 4283 = 4372
- 101 + 4271 = 4372
- 113 + 4259 = 4372
- 131 + 4241 = 4372
- 233 + 4139 = 4372
- 239 + 4133 = 4372
Showing the first eight; more decompositions exist.
