Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25590, here are decompositions:
- 7 + 25583 = 25590
- 11 + 25579 = 25590
- 13 + 25577 = 25590
- 29 + 25561 = 25590
- 53 + 25537 = 25590
- 67 + 25523 = 25590
- 127 + 25463 = 25590
- 137 + 25453 = 25590
Showing the first eight; more decompositions exist.
