Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525372, here are decompositions:
- 11 + 525361 = 525372
- 13 + 525359 = 525372
- 19 + 525353 = 525372
- 59 + 525313 = 525372
- 73 + 525299 = 525372
- 131 + 525241 = 525372
- 151 + 525221 = 525372
- 163 + 525209 = 525372
Showing the first eight; more decompositions exist.
