Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37928, here are decompositions:
- 31 + 37897 = 37928
- 67 + 37861 = 37928
- 97 + 37831 = 37928
- 181 + 37747 = 37928
- 211 + 37717 = 37928
- 229 + 37699 = 37928
- 271 + 37657 = 37928
- 337 + 37591 = 37928
Showing the first eight; more decompositions exist.
