Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25256, here are decompositions:
- 3 + 25253 = 25256
- 13 + 25243 = 25256
- 19 + 25237 = 25256
- 37 + 25219 = 25256
- 67 + 25189 = 25256
- 73 + 25183 = 25256
- 103 + 25153 = 25256
- 109 + 25147 = 25256
Showing the first eight; more decompositions exist.
