Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525378, here are decompositions:
- 5 + 525373 = 525378
- 17 + 525361 = 525378
- 19 + 525359 = 525378
- 79 + 525299 = 525378
- 131 + 525247 = 525378
- 137 + 525241 = 525378
- 157 + 525221 = 525378
- 179 + 525199 = 525378
Showing the first eight; more decompositions exist.
