Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38740, here are decompositions:
- 3 + 38737 = 38740
- 11 + 38729 = 38740
- 17 + 38723 = 38740
- 29 + 38711 = 38740
- 41 + 38699 = 38740
- 47 + 38693 = 38740
- 71 + 38669 = 38740
- 89 + 38651 = 38740
Showing the first eight; more decompositions exist.
