Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71824, here are decompositions:
- 3 + 71821 = 71824
- 17 + 71807 = 71824
- 47 + 71777 = 71824
- 83 + 71741 = 71824
- 113 + 71711 = 71824
- 131 + 71693 = 71824
- 191 + 71633 = 71824
- 227 + 71597 = 71824
Showing the first eight; more decompositions exist.
