Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18848, here are decompositions:
- 61 + 18787 = 18848
- 157 + 18691 = 18848
- 211 + 18637 = 18848
- 307 + 18541 = 18848
- 331 + 18517 = 18848
- 367 + 18481 = 18848
- 397 + 18451 = 18848
- 409 + 18439 = 18848
Showing the first eight; more decompositions exist.
