Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571872, here are decompositions:
- 5 + 571867 = 571872
- 11 + 571861 = 571872
- 19 + 571853 = 571872
- 31 + 571841 = 571872
- 61 + 571811 = 571872
- 71 + 571801 = 571872
- 73 + 571799 = 571872
- 83 + 571789 = 571872
Showing the first eight; more decompositions exist.
