Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42946, here are decompositions:
- 3 + 42943 = 42946
- 17 + 42929 = 42946
- 23 + 42923 = 42946
- 47 + 42899 = 42946
- 83 + 42863 = 42946
- 107 + 42839 = 42946
- 149 + 42797 = 42946
- 173 + 42773 = 42946
Showing the first eight; more decompositions exist.
