Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78492, here are decompositions:
- 5 + 78487 = 78492
- 13 + 78479 = 78492
- 53 + 78439 = 78492
- 151 + 78341 = 78492
- 181 + 78311 = 78492
- 191 + 78301 = 78492
- 233 + 78259 = 78492
- 251 + 78241 = 78492
Showing the first eight; more decompositions exist.
