Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25508, here are decompositions:
- 37 + 25471 = 25508
- 61 + 25447 = 25508
- 97 + 25411 = 25508
- 151 + 25357 = 25508
- 199 + 25309 = 25508
- 271 + 25237 = 25508
- 337 + 25171 = 25508
- 397 + 25111 = 25508
Showing the first eight; more decompositions exist.
