Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69870, here are decompositions:
- 11 + 69859 = 69870
- 13 + 69857 = 69870
- 23 + 69847 = 69870
- 37 + 69833 = 69870
- 41 + 69829 = 69870
- 43 + 69827 = 69870
- 61 + 69809 = 69870
- 103 + 69767 = 69870
Showing the first eight; more decompositions exist.
