Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575492, here are decompositions:
- 5 + 31575487 = 31575492
- 23 + 31575469 = 31575492
- 43 + 31575449 = 31575492
- 59 + 31575433 = 31575492
- 131 + 31575361 = 31575492
- 139 + 31575353 = 31575492
- 181 + 31575311 = 31575492
- 191 + 31575301 = 31575492
Showing the first eight; more decompositions exist.
