Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157786, here are decompositions:
- 17 + 157769 = 157786
- 47 + 157739 = 157786
- 53 + 157733 = 157786
- 107 + 157679 = 157786
- 137 + 157649 = 157786
- 149 + 157637 = 157786
- 227 + 157559 = 157786
- 263 + 157523 = 157786
Showing the first eight; more decompositions exist.
