Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69988, here are decompositions:
- 29 + 69959 = 69988
- 47 + 69941 = 69988
- 59 + 69929 = 69988
- 89 + 69899 = 69988
- 131 + 69857 = 69988
- 167 + 69821 = 69988
- 179 + 69809 = 69988
- 227 + 69761 = 69988
Showing the first eight; more decompositions exist.
