Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471928, here are decompositions:
- 79 + 31471849 = 31471928
- 97 + 31471831 = 31471928
- 307 + 31471621 = 31471928
- 337 + 31471591 = 31471928
- 349 + 31471579 = 31471928
- 379 + 31471549 = 31471928
- 541 + 31471387 = 31471928
- 571 + 31471357 = 31471928
Showing the first eight; more decompositions exist.
