Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38982, here are decompositions:
- 5 + 38977 = 38982
- 11 + 38971 = 38982
- 23 + 38959 = 38982
- 29 + 38953 = 38982
- 59 + 38923 = 38982
- 61 + 38921 = 38982
- 79 + 38903 = 38982
- 109 + 38873 = 38982
Showing the first eight; more decompositions exist.
