Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11154, here are decompositions:
- 5 + 11149 = 11154
- 23 + 11131 = 11154
- 37 + 11117 = 11154
- 41 + 11113 = 11154
- 61 + 11093 = 11154
- 67 + 11087 = 11154
- 71 + 11083 = 11154
- 83 + 11071 = 11154
Showing the first eight; more decompositions exist.
