Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25028, here are decompositions:
- 61 + 24967 = 25028
- 109 + 24919 = 25028
- 139 + 24889 = 25028
- 151 + 24877 = 25028
- 181 + 24847 = 25028
- 229 + 24799 = 25028
- 331 + 24697 = 25028
- 337 + 24691 = 25028
Showing the first eight; more decompositions exist.
