Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42930, here are decompositions:
- 7 + 42923 = 42930
- 29 + 42901 = 42930
- 31 + 42899 = 42930
- 67 + 42863 = 42930
- 71 + 42859 = 42930
- 89 + 42841 = 42930
- 101 + 42829 = 42930
- 109 + 42821 = 42930
Showing the first eight; more decompositions exist.
