Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42992, here are decompositions:
- 3 + 42989 = 42992
- 13 + 42979 = 42992
- 31 + 42961 = 42992
- 139 + 42853 = 42992
- 151 + 42841 = 42992
- 163 + 42829 = 42992
- 199 + 42793 = 42992
- 241 + 42751 = 42992
Showing the first eight; more decompositions exist.
