Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157816, here are decompositions:
- 3 + 157813 = 157816
- 17 + 157799 = 157816
- 23 + 157793 = 157816
- 47 + 157769 = 157816
- 83 + 157733 = 157816
- 137 + 157679 = 157816
- 149 + 157667 = 157816
- 167 + 157649 = 157816
Showing the first eight; more decompositions exist.
