Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18112, here are decompositions:
- 23 + 18089 = 18112
- 53 + 18059 = 18112
- 71 + 18041 = 18112
- 131 + 17981 = 18112
- 173 + 17939 = 18112
- 191 + 17921 = 18112
- 383 + 17729 = 18112
- 431 + 17681 = 18112
Showing the first eight; more decompositions exist.
