Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25650, here are decompositions:
- 7 + 25643 = 25650
- 11 + 25639 = 25650
- 17 + 25633 = 25650
- 29 + 25621 = 25650
- 41 + 25609 = 25650
- 47 + 25603 = 25650
- 61 + 25589 = 25650
- 67 + 25583 = 25650
Showing the first eight; more decompositions exist.
