Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71782, here are decompositions:
- 5 + 71777 = 71782
- 41 + 71741 = 71782
- 71 + 71711 = 71782
- 83 + 71699 = 71782
- 89 + 71693 = 71782
- 149 + 71633 = 71782
- 233 + 71549 = 71782
- 311 + 71471 = 71782
Showing the first eight; more decompositions exist.
