Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157956, here are decompositions:
- 5 + 157951 = 157956
- 23 + 157933 = 157956
- 59 + 157897 = 157956
- 67 + 157889 = 157956
- 79 + 157877 = 157956
- 89 + 157867 = 157956
- 157 + 157799 = 157956
- 163 + 157793 = 157956
Showing the first eight; more decompositions exist.
