Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47392, here are decompositions:
- 3 + 47389 = 47392
- 5 + 47387 = 47392
- 11 + 47381 = 47392
- 29 + 47363 = 47392
- 41 + 47351 = 47392
- 53 + 47339 = 47392
- 83 + 47309 = 47392
- 89 + 47303 = 47392
Showing the first eight; more decompositions exist.
