Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38980, here are decompositions:
- 3 + 38977 = 38980
- 47 + 38933 = 38980
- 59 + 38921 = 38980
- 89 + 38891 = 38980
- 107 + 38873 = 38980
- 113 + 38867 = 38980
- 197 + 38783 = 38980
- 233 + 38747 = 38980
Showing the first eight; more decompositions exist.
