Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42808, here are decompositions:
- 11 + 42797 = 42808
- 41 + 42767 = 42808
- 71 + 42737 = 42808
- 89 + 42719 = 42808
- 107 + 42701 = 42808
- 131 + 42677 = 42808
- 167 + 42641 = 42808
- 197 + 42611 = 42808
Showing the first eight; more decompositions exist.
