Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157772, here are decompositions:
- 3 + 157769 = 157772
- 103 + 157669 = 157772
- 193 + 157579 = 157772
- 211 + 157561 = 157772
- 229 + 157543 = 157772
- 283 + 157489 = 157772
- 379 + 157393 = 157772
- 409 + 157363 = 157772
Showing the first eight; more decompositions exist.
