Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27744, here are decompositions:
- 5 + 27739 = 27744
- 7 + 27737 = 27744
- 11 + 27733 = 27744
- 43 + 27701 = 27744
- 47 + 27697 = 27744
- 53 + 27691 = 27744
- 71 + 27673 = 27744
- 97 + 27647 = 27744
Showing the first eight; more decompositions exist.
