Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11290, here are decompositions:
- 3 + 11287 = 11290
- 11 + 11279 = 11290
- 17 + 11273 = 11290
- 29 + 11261 = 11290
- 47 + 11243 = 11290
- 113 + 11177 = 11290
- 131 + 11159 = 11290
- 173 + 11117 = 11290
Showing the first eight; more decompositions exist.
