Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571428, here are decompositions:
- 19 + 571409 = 571428
- 29 + 571399 = 571428
- 31 + 571397 = 571428
- 47 + 571381 = 571428
- 59 + 571369 = 571428
- 89 + 571339 = 571428
- 97 + 571331 = 571428
- 107 + 571321 = 571428
Showing the first eight; more decompositions exist.
