Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71970, here are decompositions:
- 7 + 71963 = 71970
- 23 + 71947 = 71970
- 29 + 71941 = 71970
- 37 + 71933 = 71970
- 53 + 71917 = 71970
- 61 + 71909 = 71970
- 71 + 71899 = 71970
- 83 + 71887 = 71970
Showing the first eight; more decompositions exist.
