Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39668, here are decompositions:
- 37 + 39631 = 39668
- 61 + 39607 = 39668
- 127 + 39541 = 39668
- 157 + 39511 = 39668
- 229 + 39439 = 39668
- 271 + 39397 = 39668
- 367 + 39301 = 39668
- 439 + 39229 = 39668
Showing the first eight; more decompositions exist.
