Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47488, here are decompositions:
- 29 + 47459 = 47488
- 47 + 47441 = 47488
- 71 + 47417 = 47488
- 101 + 47387 = 47488
- 107 + 47381 = 47488
- 137 + 47351 = 47488
- 149 + 47339 = 47488
- 179 + 47309 = 47488
Showing the first eight; more decompositions exist.
