Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42944, here are decompositions:
- 7 + 42937 = 42944
- 43 + 42901 = 42944
- 103 + 42841 = 42944
- 151 + 42793 = 42944
- 157 + 42787 = 42944
- 193 + 42751 = 42944
- 241 + 42703 = 42944
- 277 + 42667 = 42944
Showing the first eight; more decompositions exist.
