Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42048, here are decompositions:
- 5 + 42043 = 42048
- 29 + 42019 = 42048
- 31 + 42017 = 42048
- 67 + 41981 = 42048
- 79 + 41969 = 42048
- 89 + 41959 = 42048
- 101 + 41947 = 42048
- 107 + 41941 = 42048
Showing the first eight; more decompositions exist.
