Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42888, here are decompositions:
- 29 + 42859 = 42888
- 47 + 42841 = 42888
- 59 + 42829 = 42888
- 67 + 42821 = 42888
- 101 + 42787 = 42888
- 137 + 42751 = 42888
- 151 + 42737 = 42888
- 179 + 42709 = 42888
Showing the first eight; more decompositions exist.
