Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11380, here are decompositions:
- 11 + 11369 = 11380
- 29 + 11351 = 11380
- 59 + 11321 = 11380
- 101 + 11279 = 11380
- 107 + 11273 = 11380
- 137 + 11243 = 11380
- 167 + 11213 = 11380
- 263 + 11117 = 11380
Showing the first eight; more decompositions exist.
