Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78668, here are decompositions:
- 19 + 78649 = 78668
- 61 + 78607 = 78668
- 97 + 78571 = 78668
- 127 + 78541 = 78668
- 151 + 78517 = 78668
- 157 + 78511 = 78668
- 181 + 78487 = 78668
- 229 + 78439 = 78668
Showing the first eight; more decompositions exist.
