Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78436, here are decompositions:
- 89 + 78347 = 78436
- 233 + 78203 = 78436
- 257 + 78179 = 78436
- 263 + 78173 = 78436
- 269 + 78167 = 78436
- 419 + 78017 = 78436
- 467 + 77969 = 78436
- 503 + 77933 = 78436
Showing the first eight; more decompositions exist.
