Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78424, here are decompositions:
- 23 + 78401 = 78424
- 83 + 78341 = 78424
- 107 + 78317 = 78424
- 113 + 78311 = 78424
- 191 + 78233 = 78424
- 233 + 78191 = 78424
- 251 + 78173 = 78424
- 257 + 78167 = 78424
Showing the first eight; more decompositions exist.
