Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571780, here are decompositions:
- 3 + 571777 = 571780
- 29 + 571751 = 571780
- 59 + 571721 = 571780
- 71 + 571709 = 571780
- 101 + 571679 = 571780
- 107 + 571673 = 571780
- 179 + 571601 = 571780
- 191 + 571589 = 571780
Showing the first eight; more decompositions exist.
