Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471456, here are decompositions:
- 17 + 31471439 = 31471456
- 59 + 31471397 = 31471456
- 83 + 31471373 = 31471456
- 167 + 31471289 = 31471456
- 239 + 31471217 = 31471456
- 347 + 31471109 = 31471456
- 449 + 31471007 = 31471456
- 479 + 31470977 = 31471456
Showing the first eight; more decompositions exist.
