Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40940, here are decompositions:
- 7 + 40933 = 40940
- 13 + 40927 = 40940
- 37 + 40903 = 40940
- 43 + 40897 = 40940
- 61 + 40879 = 40940
- 73 + 40867 = 40940
- 127 + 40813 = 40940
- 139 + 40801 = 40940
Showing the first eight; more decompositions exist.
