Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38806, here are decompositions:
- 3 + 38803 = 38806
- 23 + 38783 = 38806
- 59 + 38747 = 38806
- 83 + 38723 = 38806
- 107 + 38699 = 38806
- 113 + 38693 = 38806
- 137 + 38669 = 38806
- 167 + 38639 = 38806
Showing the first eight; more decompositions exist.
