Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25804, here are decompositions:
- 3 + 25801 = 25804
- 5 + 25799 = 25804
- 11 + 25793 = 25804
- 41 + 25763 = 25804
- 71 + 25733 = 25804
- 101 + 25703 = 25804
- 131 + 25673 = 25804
- 137 + 25667 = 25804
Showing the first eight; more decompositions exist.
