Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42868, here are decompositions:
- 5 + 42863 = 42868
- 29 + 42839 = 42868
- 47 + 42821 = 42868
- 71 + 42797 = 42868
- 101 + 42767 = 42868
- 131 + 42737 = 42868
- 149 + 42719 = 42868
- 167 + 42701 = 42868
Showing the first eight; more decompositions exist.
