Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25544, here are decompositions:
- 3 + 25541 = 25544
- 7 + 25537 = 25544
- 73 + 25471 = 25544
- 97 + 25447 = 25544
- 223 + 25321 = 25544
- 241 + 25303 = 25544
- 283 + 25261 = 25544
- 307 + 25237 = 25544
Showing the first eight; more decompositions exist.
