Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13956, here are decompositions:
- 23 + 13933 = 13956
- 43 + 13913 = 13956
- 53 + 13903 = 13956
- 73 + 13883 = 13956
- 79 + 13877 = 13956
- 83 + 13873 = 13956
- 97 + 13859 = 13956
- 127 + 13829 = 13956
Showing the first eight; more decompositions exist.
