Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742456, here are decompositions:
- 7 + 8742449 = 8742456
- 89 + 8742367 = 8742456
- 97 + 8742359 = 8742456
- 103 + 8742353 = 8742456
- 109 + 8742347 = 8742456
- 139 + 8742317 = 8742456
- 193 + 8742263 = 8742456
- 197 + 8742259 = 8742456
Showing the first eight; more decompositions exist.
