Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80688, here are decompositions:
- 5 + 80683 = 80688
- 7 + 80681 = 80688
- 11 + 80677 = 80688
- 17 + 80671 = 80688
- 19 + 80669 = 80688
- 31 + 80657 = 80688
- 37 + 80651 = 80688
- 59 + 80629 = 80688
Showing the first eight; more decompositions exist.
