Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38748, here are decompositions:
- 11 + 38737 = 38748
- 19 + 38729 = 38748
- 37 + 38711 = 38748
- 41 + 38707 = 38748
- 71 + 38677 = 38748
- 79 + 38669 = 38748
- 97 + 38651 = 38748
- 109 + 38639 = 38748
Showing the first eight; more decompositions exist.
