Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471246, here are decompositions:
- 29 + 31471217 = 31471246
- 137 + 31471109 = 31471246
- 167 + 31471079 = 31471246
- 239 + 31471007 = 31471246
- 269 + 31470977 = 31471246
- 293 + 31470953 = 31471246
- 383 + 31470863 = 31471246
- 419 + 31470827 = 31471246
Showing the first eight; more decompositions exist.
