Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27788, here are decompositions:
- 37 + 27751 = 27788
- 97 + 27691 = 27788
- 157 + 27631 = 27788
- 307 + 27481 = 27788
- 331 + 27457 = 27788
- 379 + 27409 = 27788
- 421 + 27367 = 27788
- 547 + 27241 = 27788
Showing the first eight; more decompositions exist.
