Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118540, here are decompositions:
- 11 + 118529 = 118540
- 47 + 118493 = 118540
- 83 + 118457 = 118540
- 131 + 118409 = 118540
- 167 + 118373 = 118540
- 179 + 118361 = 118540
- 197 + 118343 = 118540
- 263 + 118277 = 118540
Showing the first eight; more decompositions exist.
