Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157774, here are decompositions:
- 3 + 157771 = 157774
- 5 + 157769 = 157774
- 41 + 157733 = 157774
- 53 + 157721 = 157774
- 107 + 157667 = 157774
- 137 + 157637 = 157774
- 251 + 157523 = 157774
- 317 + 157457 = 157774
Showing the first eight; more decompositions exist.
