Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12956, here are decompositions:
- 3 + 12953 = 12956
- 37 + 12919 = 12956
- 67 + 12889 = 12956
- 103 + 12853 = 12956
- 127 + 12829 = 12956
- 157 + 12799 = 12956
- 193 + 12763 = 12956
- 199 + 12757 = 12956
Showing the first eight; more decompositions exist.
