Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47518, here are decompositions:
- 5 + 47513 = 47518
- 11 + 47507 = 47518
- 17 + 47501 = 47518
- 59 + 47459 = 47518
- 101 + 47417 = 47518
- 131 + 47387 = 47518
- 137 + 47381 = 47518
- 167 + 47351 = 47518
Showing the first eight; more decompositions exist.
