Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25020, here are decompositions:
- 7 + 25013 = 25020
- 31 + 24989 = 25020
- 41 + 24979 = 25020
- 43 + 24977 = 25020
- 53 + 24967 = 25020
- 67 + 24953 = 25020
- 97 + 24923 = 25020
- 101 + 24919 = 25020
Showing the first eight; more decompositions exist.
