Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709456, here are decompositions:
- 13 + 8709443 = 8709456
- 73 + 8709383 = 8709456
- 79 + 8709377 = 8709456
- 83 + 8709373 = 8709456
- 139 + 8709317 = 8709456
- 157 + 8709299 = 8709456
- 167 + 8709289 = 8709456
- 199 + 8709257 = 8709456
Showing the first eight; more decompositions exist.
