Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39040, here are decompositions:
- 17 + 39023 = 39040
- 47 + 38993 = 39040
- 107 + 38933 = 39040
- 137 + 38903 = 39040
- 149 + 38891 = 39040
- 167 + 38873 = 39040
- 173 + 38867 = 39040
- 179 + 38861 = 39040
Showing the first eight; more decompositions exist.
