Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37728, here are decompositions:
- 11 + 37717 = 37728
- 29 + 37699 = 37728
- 37 + 37691 = 37728
- 71 + 37657 = 37728
- 79 + 37649 = 37728
- 109 + 37619 = 37728
- 137 + 37591 = 37728
- 139 + 37589 = 37728
Showing the first eight; more decompositions exist.
