Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709168, here are decompositions:
- 19 + 8709149 = 8709168
- 29 + 8709139 = 8709168
- 47 + 8709121 = 8709168
- 89 + 8709079 = 8709168
- 101 + 8709067 = 8709168
- 109 + 8709059 = 8709168
- 197 + 8708971 = 8709168
- 199 + 8708969 = 8709168
Showing the first eight; more decompositions exist.
