Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47568, here are decompositions:
- 5 + 47563 = 47568
- 41 + 47527 = 47568
- 47 + 47521 = 47568
- 61 + 47507 = 47568
- 67 + 47501 = 47568
- 71 + 47497 = 47568
- 109 + 47459 = 47568
- 127 + 47441 = 47568
Showing the first eight; more decompositions exist.
