Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69978, here are decompositions:
- 19 + 69959 = 69978
- 37 + 69941 = 69978
- 47 + 69931 = 69978
- 67 + 69911 = 69978
- 79 + 69899 = 69978
- 101 + 69877 = 69978
- 131 + 69847 = 69978
- 149 + 69829 = 69978
Showing the first eight; more decompositions exist.
