Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39000, here are decompositions:
- 7 + 38993 = 39000
- 23 + 38977 = 39000
- 29 + 38971 = 39000
- 41 + 38959 = 39000
- 47 + 38953 = 39000
- 67 + 38933 = 39000
- 79 + 38921 = 39000
- 83 + 38917 = 39000
Showing the first eight; more decompositions exist.
