Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78940, here are decompositions:
- 11 + 78929 = 78940
- 47 + 78893 = 78940
- 53 + 78887 = 78940
- 83 + 78857 = 78940
- 101 + 78839 = 78940
- 131 + 78809 = 78940
- 137 + 78803 = 78940
- 149 + 78791 = 78940
Showing the first eight; more decompositions exist.
