Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69944, here are decompositions:
- 3 + 69941 = 69944
- 13 + 69931 = 69944
- 67 + 69877 = 69944
- 97 + 69847 = 69944
- 181 + 69763 = 69944
- 283 + 69661 = 69944
- 463 + 69481 = 69944
- 487 + 69457 = 69944
Showing the first eight; more decompositions exist.
