Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38168, here are decompositions:
- 19 + 38149 = 38168
- 157 + 38011 = 38168
- 181 + 37987 = 38168
- 211 + 37957 = 38168
- 271 + 37897 = 38168
- 307 + 37861 = 38168
- 337 + 37831 = 38168
- 421 + 37747 = 38168
Showing the first eight; more decompositions exist.
