Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69984, here are decompositions:
- 43 + 69941 = 69984
- 53 + 69931 = 69984
- 73 + 69911 = 69984
- 107 + 69877 = 69984
- 127 + 69857 = 69984
- 137 + 69847 = 69984
- 151 + 69833 = 69984
- 157 + 69827 = 69984
Showing the first eight; more decompositions exist.
