Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78500, here are decompositions:
- 3 + 78497 = 78500
- 13 + 78487 = 78500
- 61 + 78439 = 78500
- 73 + 78427 = 78500
- 193 + 78307 = 78500
- 199 + 78301 = 78500
- 223 + 78277 = 78500
- 241 + 78259 = 78500
Showing the first eight; more decompositions exist.
