Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12744, here are decompositions:
- 5 + 12739 = 12744
- 23 + 12721 = 12744
- 31 + 12713 = 12744
- 41 + 12703 = 12744
- 47 + 12697 = 12744
- 73 + 12671 = 12744
- 97 + 12647 = 12744
- 103 + 12641 = 12744
Showing the first eight; more decompositions exist.
