Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42896, here are decompositions:
- 37 + 42859 = 42896
- 43 + 42853 = 42896
- 67 + 42829 = 42896
- 103 + 42793 = 42896
- 109 + 42787 = 42896
- 193 + 42703 = 42896
- 199 + 42697 = 42896
- 229 + 42667 = 42896
Showing the first eight; more decompositions exist.
