Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475666, here are decompositions:
- 43 + 31475623 = 31475666
- 67 + 31475599 = 31475666
- 223 + 31475443 = 31475666
- 349 + 31475317 = 31475666
- 379 + 31475287 = 31475666
- 457 + 31475209 = 31475666
- 577 + 31475089 = 31475666
- 613 + 31475053 = 31475666
Showing the first eight; more decompositions exist.
