Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666250, here are decompositions:
- 13 + 8666237 = 8666250
- 31 + 8666219 = 8666250
- 67 + 8666183 = 8666250
- 83 + 8666167 = 8666250
- 97 + 8666153 = 8666250
- 113 + 8666137 = 8666250
- 157 + 8666093 = 8666250
- 181 + 8666069 = 8666250
Showing the first eight; more decompositions exist.
