Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78506, here are decompositions:
- 19 + 78487 = 78506
- 67 + 78439 = 78506
- 79 + 78427 = 78506
- 139 + 78367 = 78506
- 199 + 78307 = 78506
- 223 + 78283 = 78506
- 229 + 78277 = 78506
- 277 + 78229 = 78506
Showing the first eight; more decompositions exist.
