Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78918, here are decompositions:
- 17 + 78901 = 78918
- 29 + 78889 = 78918
- 31 + 78887 = 78918
- 41 + 78877 = 78918
- 61 + 78857 = 78918
- 79 + 78839 = 78918
- 109 + 78809 = 78918
- 127 + 78791 = 78918
Showing the first eight; more decompositions exist.
