Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42994, here are decompositions:
- 5 + 42989 = 42994
- 41 + 42953 = 42994
- 71 + 42923 = 42994
- 131 + 42863 = 42994
- 173 + 42821 = 42994
- 197 + 42797 = 42994
- 227 + 42767 = 42994
- 251 + 42743 = 42994
Showing the first eight; more decompositions exist.
