Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125028, here are decompositions:
- 11 + 125017 = 125028
- 37 + 124991 = 125028
- 41 + 124987 = 125028
- 47 + 124981 = 125028
- 109 + 124919 = 125028
- 131 + 124897 = 125028
- 181 + 124847 = 125028
- 229 + 124799 = 125028
Showing the first eight; more decompositions exist.
