Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42906, here are decompositions:
- 5 + 42901 = 42906
- 7 + 42899 = 42906
- 43 + 42863 = 42906
- 47 + 42859 = 42906
- 53 + 42853 = 42906
- 67 + 42839 = 42906
- 109 + 42797 = 42906
- 113 + 42793 = 42906
Showing the first eight; more decompositions exist.
