Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66980, here are decompositions:
- 3 + 66977 = 66980
- 7 + 66973 = 66980
- 31 + 66949 = 66980
- 37 + 66943 = 66980
- 61 + 66919 = 66980
- 97 + 66883 = 66980
- 103 + 66877 = 66980
- 127 + 66853 = 66980
Showing the first eight; more decompositions exist.
