Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74970, here are decompositions:
- 11 + 74959 = 74970
- 29 + 74941 = 74970
- 37 + 74933 = 74970
- 41 + 74929 = 74970
- 47 + 74923 = 74970
- 67 + 74903 = 74970
- 73 + 74897 = 74970
- 79 + 74891 = 74970
Showing the first eight; more decompositions exist.
