Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69940, here are decompositions:
- 11 + 69929 = 69940
- 29 + 69911 = 69940
- 41 + 69899 = 69940
- 83 + 69857 = 69940
- 107 + 69833 = 69940
- 113 + 69827 = 69940
- 131 + 69809 = 69940
- 173 + 69767 = 69940
Showing the first eight; more decompositions exist.
