Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55878, here are decompositions:
- 7 + 55871 = 55878
- 29 + 55849 = 55878
- 41 + 55837 = 55878
- 59 + 55819 = 55878
- 61 + 55817 = 55878
- 71 + 55807 = 55878
- 79 + 55799 = 55878
- 157 + 55721 = 55878
Showing the first eight; more decompositions exist.
