Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75040, here are decompositions:
- 3 + 75037 = 75040
- 11 + 75029 = 75040
- 23 + 75017 = 75040
- 29 + 75011 = 75040
- 107 + 74933 = 75040
- 137 + 74903 = 75040
- 149 + 74891 = 75040
- 167 + 74873 = 75040
Showing the first eight; more decompositions exist.
