Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25178, here are decompositions:
- 7 + 25171 = 25178
- 31 + 25147 = 25178
- 61 + 25117 = 25178
- 67 + 25111 = 25178
- 199 + 24979 = 25178
- 211 + 24967 = 25178
- 271 + 24907 = 25178
- 331 + 24847 = 25178
Showing the first eight; more decompositions exist.
