Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77140, here are decompositions:
- 3 + 77137 = 77140
- 47 + 77093 = 77140
- 59 + 77081 = 77140
- 71 + 77069 = 77140
- 137 + 77003 = 77140
- 149 + 76991 = 77140
- 179 + 76961 = 77140
- 191 + 76949 = 77140
Showing the first eight; more decompositions exist.
