Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70980, here are decompositions:
- 11 + 70969 = 70980
- 23 + 70957 = 70980
- 29 + 70951 = 70980
- 31 + 70949 = 70980
- 43 + 70937 = 70980
- 59 + 70921 = 70980
- 61 + 70919 = 70980
- 67 + 70913 = 70980
Showing the first eight; more decompositions exist.
