Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25582, here are decompositions:
- 3 + 25579 = 25582
- 5 + 25577 = 25582
- 41 + 25541 = 25582
- 59 + 25523 = 25582
- 113 + 25469 = 25582
- 173 + 25409 = 25582
- 191 + 25391 = 25582
- 233 + 25349 = 25582
Showing the first eight; more decompositions exist.
