Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157694, here are decompositions:
- 67 + 157627 = 157694
- 151 + 157543 = 157694
- 181 + 157513 = 157694
- 211 + 157483 = 157694
- 283 + 157411 = 157694
- 331 + 157363 = 157694
- 367 + 157327 = 157694
- 373 + 157321 = 157694
Showing the first eight; more decompositions exist.
