Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157744, here are decompositions:
- 5 + 157739 = 157744
- 11 + 157733 = 157744
- 23 + 157721 = 157744
- 107 + 157637 = 157744
- 173 + 157571 = 157744
- 311 + 157433 = 157744
- 317 + 157427 = 157744
- 467 + 157277 = 157744
Showing the first eight; more decompositions exist.
