Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71568, here are decompositions:
- 5 + 71563 = 71568
- 17 + 71551 = 71568
- 19 + 71549 = 71568
- 31 + 71537 = 71568
- 41 + 71527 = 71568
- 89 + 71479 = 71568
- 97 + 71471 = 71568
- 131 + 71437 = 71568
Showing the first eight; more decompositions exist.
