Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27668, here are decompositions:
- 37 + 27631 = 27668
- 127 + 27541 = 27668
- 139 + 27529 = 27668
- 181 + 27487 = 27668
- 211 + 27457 = 27668
- 241 + 27427 = 27668
- 271 + 27397 = 27668
- 307 + 27361 = 27668
Showing the first eight; more decompositions exist.
