Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27646, here are decompositions:
- 29 + 27617 = 27646
- 107 + 27539 = 27646
- 137 + 27509 = 27646
- 167 + 27479 = 27646
- 197 + 27449 = 27646
- 239 + 27407 = 27646
- 317 + 27329 = 27646
- 347 + 27299 = 27646
Showing the first eight; more decompositions exist.
