Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 574, here are decompositions:
- 3 + 571 = 574
- 5 + 569 = 574
- 11 + 563 = 574
- 17 + 557 = 574
- 53 + 521 = 574
- 71 + 503 = 574
- 83 + 491 = 574
- 107 + 467 = 574
Showing the first eight; more decompositions exist.
