Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25388, here are decompositions:
- 31 + 25357 = 25388
- 67 + 25321 = 25388
- 79 + 25309 = 25388
- 127 + 25261 = 25388
- 151 + 25237 = 25388
- 199 + 25189 = 25388
- 241 + 25147 = 25388
- 271 + 25117 = 25388
Showing the first eight; more decompositions exist.
