Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39072, here are decompositions:
- 29 + 39043 = 39072
- 31 + 39041 = 39072
- 53 + 39019 = 39072
- 79 + 38993 = 39072
- 101 + 38971 = 39072
- 113 + 38959 = 39072
- 139 + 38933 = 39072
- 149 + 38923 = 39072
Showing the first eight; more decompositions exist.
