Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38812, here are decompositions:
- 29 + 38783 = 38812
- 83 + 38729 = 38812
- 89 + 38723 = 38812
- 101 + 38711 = 38812
- 113 + 38699 = 38812
- 173 + 38639 = 38812
- 251 + 38561 = 38812
- 269 + 38543 = 38812
Showing the first eight; more decompositions exist.
