Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8444, here are decompositions:
- 13 + 8431 = 8444
- 67 + 8377 = 8444
- 127 + 8317 = 8444
- 151 + 8293 = 8444
- 157 + 8287 = 8444
- 181 + 8263 = 8444
- 211 + 8233 = 8444
- 223 + 8221 = 8444
Showing the first eight; more decompositions exist.
