Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157960, here are decompositions:
- 29 + 157931 = 157960
- 53 + 157907 = 157960
- 59 + 157901 = 157960
- 71 + 157889 = 157960
- 83 + 157877 = 157960
- 137 + 157823 = 157960
- 167 + 157793 = 157960
- 191 + 157769 = 157960
Showing the first eight; more decompositions exist.
