Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38000, here are decompositions:
- 3 + 37997 = 38000
- 7 + 37993 = 38000
- 13 + 37987 = 38000
- 37 + 37963 = 38000
- 43 + 37957 = 38000
- 103 + 37897 = 38000
- 139 + 37861 = 38000
- 283 + 37717 = 38000
Showing the first eight; more decompositions exist.
