Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709728, here are decompositions:
- 7 + 8709721 = 8709728
- 31 + 8709697 = 8709728
- 367 + 8709361 = 8709728
- 439 + 8709289 = 8709728
- 457 + 8709271 = 8709728
- 499 + 8709229 = 8709728
- 541 + 8709187 = 8709728
- 607 + 8709121 = 8709728
Showing the first eight; more decompositions exist.
