Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78984, here are decompositions:
- 5 + 78979 = 78984
- 7 + 78977 = 78984
- 43 + 78941 = 78984
- 83 + 78901 = 78984
- 97 + 78887 = 78984
- 107 + 78877 = 78984
- 127 + 78857 = 78984
- 131 + 78853 = 78984
Showing the first eight; more decompositions exist.
