Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38800, here are decompositions:
- 17 + 38783 = 38800
- 53 + 38747 = 38800
- 71 + 38729 = 38800
- 89 + 38711 = 38800
- 101 + 38699 = 38800
- 107 + 38693 = 38800
- 131 + 38669 = 38800
- 149 + 38651 = 38800
Showing the first eight; more decompositions exist.
