Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42908, here are decompositions:
- 7 + 42901 = 42908
- 67 + 42841 = 42908
- 79 + 42829 = 42908
- 157 + 42751 = 42908
- 181 + 42727 = 42908
- 199 + 42709 = 42908
- 211 + 42697 = 42908
- 241 + 42667 = 42908
Showing the first eight; more decompositions exist.
