Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38940, here are decompositions:
- 7 + 38933 = 38940
- 17 + 38923 = 38940
- 19 + 38921 = 38940
- 23 + 38917 = 38940
- 37 + 38903 = 38940
- 67 + 38873 = 38940
- 73 + 38867 = 38940
- 79 + 38861 = 38940
Showing the first eight; more decompositions exist.
