Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571842, here are decompositions:
- 31 + 571811 = 571842
- 41 + 571801 = 571842
- 43 + 571799 = 571842
- 53 + 571789 = 571842
- 59 + 571783 = 571842
- 83 + 571759 = 571842
- 101 + 571741 = 571842
- 163 + 571679 = 571842
Showing the first eight; more decompositions exist.
