Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47444, here are decompositions:
- 3 + 47441 = 47444
- 13 + 47431 = 47444
- 37 + 47407 = 47444
- 127 + 47317 = 47444
- 151 + 47293 = 47444
- 157 + 47287 = 47444
- 193 + 47251 = 47444
- 223 + 47221 = 47444
Showing the first eight; more decompositions exist.
