Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471492, here are decompositions:
- 11 + 31471481 = 31471492
- 23 + 31471469 = 31471492
- 53 + 31471439 = 31471492
- 131 + 31471361 = 31471492
- 383 + 31471109 = 31471492
- 401 + 31471091 = 31471492
- 449 + 31471043 = 31471492
- 461 + 31471031 = 31471492
Showing the first eight; more decompositions exist.
