Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47530, here are decompositions:
- 3 + 47527 = 47530
- 17 + 47513 = 47530
- 23 + 47507 = 47530
- 29 + 47501 = 47530
- 71 + 47459 = 47530
- 89 + 47441 = 47530
- 113 + 47417 = 47530
- 149 + 47381 = 47530
Showing the first eight; more decompositions exist.
