Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8250, here are decompositions:
- 7 + 8243 = 8250
- 13 + 8237 = 8250
- 17 + 8233 = 8250
- 19 + 8231 = 8250
- 29 + 8221 = 8250
- 31 + 8219 = 8250
- 41 + 8209 = 8250
- 59 + 8191 = 8250
Showing the first eight; more decompositions exist.
