Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25392, here are decompositions:
- 19 + 25373 = 25392
- 43 + 25349 = 25392
- 53 + 25339 = 25392
- 71 + 25321 = 25392
- 83 + 25309 = 25392
- 89 + 25303 = 25392
- 131 + 25261 = 25392
- 139 + 25253 = 25392
Showing the first eight; more decompositions exist.
