Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111538, here are decompositions:
- 5 + 111533 = 111538
- 17 + 111521 = 111538
- 29 + 111509 = 111538
- 41 + 111497 = 111538
- 47 + 111491 = 111538
- 71 + 111467 = 111538
- 107 + 111431 = 111538
- 191 + 111347 = 111538
Showing the first eight; more decompositions exist.
