Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471060, here are decompositions:
- 17 + 31471043 = 31471060
- 29 + 31471031 = 31471060
- 53 + 31471007 = 31471060
- 59 + 31471001 = 31471060
- 83 + 31470977 = 31471060
- 107 + 31470953 = 31471060
- 149 + 31470911 = 31471060
- 191 + 31470869 = 31471060
Showing the first eight; more decompositions exist.
