Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78016, here are decompositions:
- 17 + 77999 = 78016
- 47 + 77969 = 78016
- 83 + 77933 = 78016
- 149 + 77867 = 78016
- 167 + 77849 = 78016
- 233 + 77783 = 78016
- 269 + 77747 = 78016
- 293 + 77723 = 78016
Showing the first eight; more decompositions exist.
