Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524768, here are decompositions:
- 5 + 31524763 = 31524768
- 47 + 31524721 = 31524768
- 127 + 31524641 = 31524768
- 181 + 31524587 = 31524768
- 199 + 31524569 = 31524768
- 227 + 31524541 = 31524768
- 251 + 31524517 = 31524768
- 269 + 31524499 = 31524768
Showing the first eight; more decompositions exist.
