Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69780, here are decompositions:
- 13 + 69767 = 69780
- 17 + 69763 = 69780
- 19 + 69761 = 69780
- 41 + 69739 = 69780
- 43 + 69737 = 69780
- 71 + 69709 = 69780
- 83 + 69697 = 69780
- 89 + 69691 = 69780
Showing the first eight; more decompositions exist.
