Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69930, here are decompositions:
- 19 + 69911 = 69930
- 31 + 69899 = 69930
- 53 + 69877 = 69930
- 71 + 69859 = 69930
- 73 + 69857 = 69930
- 83 + 69847 = 69930
- 97 + 69833 = 69930
- 101 + 69829 = 69930
Showing the first eight; more decompositions exist.
