Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524440, here are decompositions:
- 37 + 31524403 = 31524440
- 97 + 31524343 = 31524440
- 109 + 31524331 = 31524440
- 139 + 31524301 = 31524440
- 163 + 31524277 = 31524440
- 307 + 31524133 = 31524440
- 349 + 31524091 = 31524440
- 397 + 31524043 = 31524440
Showing the first eight; more decompositions exist.
