Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11512, here are decompositions:
- 23 + 11489 = 11512
- 29 + 11483 = 11512
- 41 + 11471 = 11512
- 89 + 11423 = 11512
- 101 + 11411 = 11512
- 113 + 11399 = 11512
- 191 + 11321 = 11512
- 233 + 11279 = 11512
Showing the first eight; more decompositions exist.
