Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717688, here are decompositions:
- 11 + 8717677 = 8717688
- 97 + 8717591 = 8717688
- 131 + 8717557 = 8717688
- 137 + 8717551 = 8717688
- 157 + 8717531 = 8717688
- 167 + 8717521 = 8717688
- 179 + 8717509 = 8717688
- 197 + 8717491 = 8717688
Showing the first eight; more decompositions exist.
