Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38838, here are decompositions:
- 5 + 38833 = 38838
- 17 + 38821 = 38838
- 47 + 38791 = 38838
- 71 + 38767 = 38838
- 89 + 38749 = 38838
- 101 + 38737 = 38838
- 109 + 38729 = 38838
- 127 + 38711 = 38838
Showing the first eight; more decompositions exist.
