Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118838, here are decompositions:
- 7 + 118831 = 118838
- 19 + 118819 = 118838
- 37 + 118801 = 118838
- 151 + 118687 = 118838
- 157 + 118681 = 118838
- 367 + 118471 = 118838
- 409 + 118429 = 118838
- 439 + 118399 = 118838
Showing the first eight; more decompositions exist.
