Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78470, here are decompositions:
- 3 + 78467 = 78470
- 31 + 78439 = 78470
- 43 + 78427 = 78470
- 103 + 78367 = 78470
- 163 + 78307 = 78470
- 193 + 78277 = 78470
- 211 + 78259 = 78470
- 229 + 78241 = 78470
Showing the first eight; more decompositions exist.
