Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25472, here are decompositions:
- 3 + 25469 = 25472
- 19 + 25453 = 25472
- 61 + 25411 = 25472
- 151 + 25321 = 25472
- 163 + 25309 = 25472
- 211 + 25261 = 25472
- 229 + 25243 = 25472
- 283 + 25189 = 25472
Showing the first eight; more decompositions exist.
