Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11428, here are decompositions:
- 5 + 11423 = 11428
- 17 + 11411 = 11428
- 29 + 11399 = 11428
- 59 + 11369 = 11428
- 107 + 11321 = 11428
- 149 + 11279 = 11428
- 167 + 11261 = 11428
- 251 + 11177 = 11428
Showing the first eight; more decompositions exist.
