Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38880, here are decompositions:
- 7 + 38873 = 38880
- 13 + 38867 = 38880
- 19 + 38861 = 38880
- 29 + 38851 = 38880
- 41 + 38839 = 38880
- 47 + 38833 = 38880
- 59 + 38821 = 38880
- 89 + 38791 = 38880
Showing the first eight; more decompositions exist.
