Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89980, here are decompositions:
- 3 + 89977 = 89980
- 17 + 89963 = 89980
- 41 + 89939 = 89980
- 71 + 89909 = 89980
- 83 + 89897 = 89980
- 89 + 89891 = 89980
- 113 + 89867 = 89980
- 131 + 89849 = 89980
Showing the first eight; more decompositions exist.
