Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77112, here are decompositions:
- 11 + 77101 = 77112
- 19 + 77093 = 77112
- 31 + 77081 = 77112
- 43 + 77069 = 77112
- 71 + 77041 = 77112
- 83 + 77029 = 77112
- 89 + 77023 = 77112
- 109 + 77003 = 77112
Showing the first eight; more decompositions exist.
