Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25860, here are decompositions:
- 11 + 25849 = 25860
- 13 + 25847 = 25860
- 19 + 25841 = 25860
- 41 + 25819 = 25860
- 59 + 25801 = 25860
- 61 + 25799 = 25860
- 67 + 25793 = 25860
- 89 + 25771 = 25860
Showing the first eight; more decompositions exist.
