Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940, here are decompositions:
- 3 + 937 = 940
- 11 + 929 = 940
- 29 + 911 = 940
- 53 + 887 = 940
- 59 + 881 = 940
- 83 + 857 = 940
- 101 + 839 = 940
- 113 + 827 = 940
Showing the first eight; more decompositions exist.
