Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69720, here are decompositions:
- 11 + 69709 = 69720
- 23 + 69697 = 69720
- 29 + 69691 = 69720
- 43 + 69677 = 69720
- 59 + 69661 = 69720
- 67 + 69653 = 69720
- 97 + 69623 = 69720
- 127 + 69593 = 69720
Showing the first eight; more decompositions exist.
