Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78342, here are decompositions:
- 31 + 78311 = 78342
- 41 + 78301 = 78342
- 59 + 78283 = 78342
- 83 + 78259 = 78342
- 101 + 78241 = 78342
- 109 + 78233 = 78342
- 113 + 78229 = 78342
- 139 + 78203 = 78342
Showing the first eight; more decompositions exist.
