Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25444, here are decompositions:
- 5 + 25439 = 25444
- 53 + 25391 = 25444
- 71 + 25373 = 25444
- 101 + 25343 = 25444
- 137 + 25307 = 25444
- 191 + 25253 = 25444
- 197 + 25247 = 25444
- 281 + 25163 = 25444
Showing the first eight; more decompositions exist.
