Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11408, here are decompositions:
- 79 + 11329 = 11408
- 97 + 11311 = 11408
- 109 + 11299 = 11408
- 151 + 11257 = 11408
- 157 + 11251 = 11408
- 211 + 11197 = 11408
- 277 + 11131 = 11408
- 337 + 11071 = 11408
Showing the first eight; more decompositions exist.
