Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524792, here are decompositions:
- 29 + 31524763 = 31524792
- 71 + 31524721 = 31524792
- 149 + 31524643 = 31524792
- 151 + 31524641 = 31524792
- 223 + 31524569 = 31524792
- 251 + 31524541 = 31524792
- 269 + 31524523 = 31524792
- 283 + 31524509 = 31524792
Showing the first eight; more decompositions exist.
