Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25802, here are decompositions:
- 3 + 25799 = 25802
- 31 + 25771 = 25802
- 43 + 25759 = 25802
- 61 + 25741 = 25802
- 109 + 25693 = 25802
- 163 + 25639 = 25802
- 181 + 25621 = 25802
- 193 + 25609 = 25802
Showing the first eight; more decompositions exist.
