Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742384, here are decompositions:
- 5 + 8742379 = 8742384
- 17 + 8742367 = 8742384
- 31 + 8742353 = 8742384
- 37 + 8742347 = 8742384
- 67 + 8742317 = 8742384
- 71 + 8742313 = 8742384
- 191 + 8742193 = 8742384
- 197 + 8742187 = 8742384
Showing the first eight; more decompositions exist.
