Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42956, here are decompositions:
- 3 + 42953 = 42956
- 13 + 42943 = 42956
- 19 + 42937 = 42956
- 97 + 42859 = 42956
- 103 + 42853 = 42956
- 127 + 42829 = 42956
- 163 + 42793 = 42956
- 229 + 42727 = 42956
Showing the first eight; more decompositions exist.
