Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47584, here are decompositions:
- 3 + 47581 = 47584
- 41 + 47543 = 47584
- 71 + 47513 = 47584
- 83 + 47501 = 47584
- 167 + 47417 = 47584
- 197 + 47387 = 47584
- 233 + 47351 = 47584
- 281 + 47303 = 47584
Showing the first eight; more decompositions exist.
