Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47520, here are decompositions:
- 7 + 47513 = 47520
- 13 + 47507 = 47520
- 19 + 47501 = 47520
- 23 + 47497 = 47520
- 29 + 47491 = 47520
- 61 + 47459 = 47520
- 79 + 47441 = 47520
- 89 + 47431 = 47520
Showing the first eight; more decompositions exist.
