Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25822, here are decompositions:
- 3 + 25819 = 25822
- 23 + 25799 = 25822
- 29 + 25793 = 25822
- 59 + 25763 = 25822
- 89 + 25733 = 25822
- 149 + 25673 = 25822
- 179 + 25643 = 25822
- 233 + 25589 = 25822
Showing the first eight; more decompositions exist.
