Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47538, here are decompositions:
- 5 + 47533 = 47538
- 11 + 47527 = 47538
- 17 + 47521 = 47538
- 31 + 47507 = 47538
- 37 + 47501 = 47538
- 41 + 47497 = 47538
- 47 + 47491 = 47538
- 79 + 47459 = 47538
Showing the first eight; more decompositions exist.
