Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77880, here are decompositions:
- 13 + 77867 = 77880
- 17 + 77863 = 77880
- 31 + 77849 = 77880
- 41 + 77839 = 77880
- 67 + 77813 = 77880
- 79 + 77801 = 77880
- 83 + 77797 = 77880
- 97 + 77783 = 77880
Showing the first eight; more decompositions exist.
