Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38138, here are decompositions:
- 19 + 38119 = 38138
- 127 + 38011 = 38138
- 151 + 37987 = 38138
- 181 + 37957 = 38138
- 241 + 37897 = 38138
- 277 + 37861 = 38138
- 307 + 37831 = 38138
- 421 + 37717 = 38138
Showing the first eight; more decompositions exist.
