Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42894, here are decompositions:
- 31 + 42863 = 42894
- 41 + 42853 = 42894
- 53 + 42841 = 42894
- 73 + 42821 = 42894
- 97 + 42797 = 42894
- 101 + 42793 = 42894
- 107 + 42787 = 42894
- 127 + 42767 = 42894
Showing the first eight; more decompositions exist.
