Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157782, here are decompositions:
- 11 + 157771 = 157782
- 13 + 157769 = 157782
- 43 + 157739 = 157782
- 61 + 157721 = 157782
- 103 + 157679 = 157782
- 113 + 157669 = 157782
- 211 + 157571 = 157782
- 223 + 157559 = 157782
Showing the first eight; more decompositions exist.
