Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25636, here are decompositions:
- 3 + 25633 = 25636
- 47 + 25589 = 25636
- 53 + 25583 = 25636
- 59 + 25577 = 25636
- 113 + 25523 = 25636
- 167 + 25469 = 25636
- 173 + 25463 = 25636
- 179 + 25457 = 25636
Showing the first eight; more decompositions exist.
