Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80988, here are decompositions:
- 59 + 80929 = 80988
- 71 + 80917 = 80988
- 79 + 80909 = 80988
- 139 + 80849 = 80988
- 157 + 80831 = 80988
- 179 + 80809 = 80988
- 199 + 80789 = 80988
- 211 + 80777 = 80988
Showing the first eight; more decompositions exist.
