Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717784, here are decompositions:
- 11 + 8717773 = 8717784
- 17 + 8717767 = 8717784
- 37 + 8717747 = 8717784
- 41 + 8717743 = 8717784
- 43 + 8717741 = 8717784
- 67 + 8717717 = 8717784
- 107 + 8717677 = 8717784
- 151 + 8717633 = 8717784
Showing the first eight; more decompositions exist.
