Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78028, here are decompositions:
- 11 + 78017 = 78028
- 29 + 77999 = 78028
- 59 + 77969 = 78028
- 179 + 77849 = 78028
- 227 + 77801 = 78028
- 281 + 77747 = 78028
- 317 + 77711 = 78028
- 347 + 77681 = 78028
Showing the first eight; more decompositions exist.
